Sonos speakers and applications on different subnets (VLAN's)

[Bull]

@qinn No, at the moment I don't have any positive results, it's quite frustrating, I don't know if I have a problem with netgear GS110TP switches or with pfsense I have it configured in a vmware environment with vlan(4096) and this may be blocking multicast to the router in vmware. I don't know how to continue I'm absolutely blocked, I've been trying and testing for a couple of weeks and starting over.

I need a rest, think so.

Did you turn the port to "promiscuous mode" in VMware for pfSense? That bit me in the butt once, a lesson I will not forget.

[Qinn]

@tim-mcmanus In my setup(s) I do not use VMware at the moment, so I cannot advise. In theory the switch should not play a part, when it is in the private (RFC1918) subnet(s) and pfSense is controlling these subnets. So IGMP snooping should not be needed, the IGMP proxy or PIMD should do that part.
Have you checked what multicast is send (wireshark)? That's how I analyzed that 239.255.255.0 was used by Sonos and that native IGMP proxy used by pfSense did not traversed it over the subnets.

[Bull]

@tim-mcmanus yes, promiscuous mode is enable on vmware NIC, anyway I haven't problems with unicast, I can ping and have conectivity across vlans inside and outside of the vmware. So I don't understand were the multicast cannot be routed

[Bull]

@qinn thank you, I'll try to disable IGMP on these switches later on, I let you know if it's work.

Hi Qinn I'll try to using your guide with pim to configure a similar problem in my network with google devices and Logitech Media server, I hope that this works.

Thanks.

Btw could you give a description of your setup?

I have a ISP router on bridge mode conecting directly to a vmware nic (MODEM LAN 192.168.0.1/24) this interface works as PPPOE and route to modem network. (EM1)

the other nic i have created to vnic both in vlan 4095, the first one EM0 is de MGMT Lan (192.168.1.1/24) and the other vnic EM2 is configured as vlan 4095 and I've been created 5 port in the following tagged Vlan (10,20,30,40 and 50) from 192.168.10 to 50.1 subnet.

this nic is connected to a Netgear GPT110PT in port 6 vlan 10,20,30,40,50 as tagged an 1 untagged, I have a LAGG vlan 20 too connected to a NAS. from this switch is connected another one in port 1 vlan 10,20,30,40,50 as tagged an 1 untagged to port 8.

In port 5 from this second switch, I have a Ubiquiti AP with some wifi ssid configured with vlans 30,40,50, this port also configured with vlans as 10,20,30,40,50 as tagged an 1 untagged

both swicthes have IGMP Snooping enabled, configured IGMP vlan configuration for vlan 1,30,50 (testing at the moment) with querier enable and queriers enable and configured with vlan 1,30 and 50 pointing to each router ip subnet address 1,1 for vlan 1 30.1 for vlan 30...

May be this is a little confuse without a diagram but I don't have any software to have a grafical view of my network.

Many thanks

There is plenty of free software or even just websites that would allow you to draw your network.
Here are 2 you can do it in pure ascii
https://textik.com/

Disable IGMP Snooping on physical Switches didn't change anything.

Is possible that the problem is that I'm using default vlan 1 as default router ip network and this vlan don't work as spected with multicasting?

I think so from vmware point of view the configuration of the vnic on vlan 4095 is correct.

many thanks
Bull

[johnpoz]

4095 on a vswitch will pass all tags to the VMs connected to the switch.

To be honest not a fan of dicking with multicast like to feed it into other Layer 2 networks. If the companies want to be so short sighted to think that their users don't run multiple segments and a way for access through a firewall and different segments then either don't use them.. I mean how hard would it be to let the app put in the IP, and clearly lists what ports need to be allowed, etc.

Or if you really want to use them, then just put all the devices on that L2... I do this with printer - its on the one wireless network.. So if you want to print you just need to make sure your on that SSID.. Not really a big deal... For example when want to control my roku devices with my phone or tables I join the roku vlan.

[Bull]

@johnpoz I'm agree with you but looking for the future where more and more IOT devices could be connected in a home lan without any "security" control, would be necesary that the developers that works in security bring to those people that want more security in their home a tool that would be it posible. The company or solution that bring that, win the battle.

I know that is not normal that the mayority of the people had segmented the lan network in their home to have a better view/control of their devices, but how many people had an antivirus installed in their system some years ago?

I'm not want to desviate from the thread, unfortunatly this morning the multicast was working with google devices, I don't know how, I leave home and shutdown the laptop and now I cannot see the chromecast, so... I don't know where my problem is.

[Bull]

@Qinn ,only to compare with your confg. this is normal situation with "no traffic" states in the upd/multicast ?

Thank you Qinn for posting this! PIMD worked for me after hours and hours of work trying to get my HEOS (Denon's version of "Sonos") working across VLANs.

Is there anything that I need to do to ensure that PIMD loads with the correct settings everytime my pfSense restarts or is updated?

[dennypage]

@nick13 PIM isn't needed (or desired) for HEOS. All that is needed for HEOS is Avahi with reflection enabled. Following discovery, which is mdns based, HEOS is point to point rather than multicast.

[nick13]

@dennypage I've had Avahi installed with reflection enabled and have been unable to get it to work until I also turn on PIMD. When I kill PIMD the HEOS app quits recognizing my receivers on the other vlan.

Do you have any thoughts why that might be?

As a side note, I figured out the answer to my question that I posted by adding the PIMD start command to the config.xml file.

[dennypage]

@nick13

Check these things:

You have firewall interfaces in both the client subnet (where your iPhone is) and the server subnet (where the HEOS device is).

You have Avahi (2.0.0_2) with the allowed interfaces set to include both the client subnet and the server subnet.

You have "Enable" and "Enable reflection" checked in the Avahi configuration.

You do not have "Disable IPv4" checked in the Avahi configuration.

You do not have anything defined in the "Advanced settings" section of the Avahi configuration.

You have added rules to allow ptp packets from the clients to the HEOS device you are trying to control.

You have restarted or disconnected/reconnected both HEOS clients and servers after changing the any of the above.

Nice that it helped you, the config file that PIMD is using will probably be removed once you update pfSense.

[pr3dict]

2 questions...

I have PFsense running in an esxi environment and I don't have my network adapter in promiscuous mode. I have the pcie ethernet adapter as a directpath i/o dedicated device. Essentially vmware doesnt even see the device anymore and it as if it's native to the pfsense host machine. This should be good from my understanding?

question 2: Has anyone tried this with a network cablecard tuner? I'm trying to get my hdhomerun to work with igmpproxy and pfsense doesnt seem to be sending any of the multicast traffic.

[denix]

First of all, huge thanks to Qinn and others for figuring this out and providing instructions!

Second, I've read and followed all the instructions here and in other threads w/o any success. So, after days of trials and errors I'd like to ask for some help.

My configuration is slightly different - I need to traverse multicast for Sonos between a real no-VLAN subnet and a dedicated VLAN subnet within. I.e. there's a regular LAN where no-VLAN devices live (it's actually a Default VLAN 1 on the switch, but untagged), bound to "igb1" interface. That's where controller resides in the form of an Android app. And there's a dedicated tagged VLAN 10 for Sonos devices, bound to "igb1.10" interface. LAN on igb1 is 192.168.0.0/24 and VLAN10 on igb1.10 is 192.168.10.0/24. pfSense is 192.168.0.1 and 192.168.10.1 on each interface. Both subnets have DHCP server, both are fully open in Firewall - I can ping and send unicast traffic between those 2 subnets fine.

Now, when I configure PIMD on igb1 and igb1.10, it reports that subnet for the second one is 192.168.10, while subnet for the first one is 192.168. Which leads me to believe that PIMD somehow considers VLAN10 to be "shadowed" inside LAN, not a separate subnet and refuses to retransmit multicast between them.

I tried different combinations of "altnet" configuration specified w/o much success. After a while I see some other Android devices joining multicast groups reported by PIMD, but Sonos still doesn't work - an Android controller app on LAN can't find any Sonos device on VLAN10.

I'd like to avoid the need to tag everything on LAN to make it a dedicated VLAN subnet. Essentially that would mean VLAN 1 as a real subnet, start tagging everything, create "igb1.1" interface for it and close LAN "igb1" down. Supposedly, that would work, as reported by others - VLAN1 <-> VLAN10, igb1.1 <-> igb1.10. Unfortunately, that means extra work, lots of gear configuration and some downtime to my network.

So, I would appreciate any suggestions and ideas for how to make it work with the setup I have right now - LAN <-> VLAN10, igb1 <-> igb1.10. Thanks in advance and please let me know what you think!

[Qinn]

@denix Could you post the messages you receive from PIMD and could you post the config file of PIMD

A VLAN that is not tagged is not a VLAN ;) , but tagging or not should not really matter as tagging happens when it leaves the subnet and traverses the switch.

[denix]

@Qinn sorry if my explanation wasn't very clear. Yes, I was trying to say that LAN carries both VLAN-tagged traffic, as well as untagged.

Originally I had all Sonos speakers in a separate VLAN10 tagged subnet, while other devices including Android controller app in untagged LAN.

Tired of trying to make it work, I ended up placing WiFi devices into own VLAN40 tagged subnet. Now testing PIMD with VLAN10 <-> VLAN40 and still no luck.

VLAN10 = 192.168.10.0/24 (Sonos speakers)
VLAN40 = 192.168.40.0/24 (Android control app)

pfSense has IP of x.x.x.1 on each interface. Both subnets are fully open to each other for unidirectional traffic.

Here's my config (tried many different variants of enabling/disabling different options):

phyint igb0 disable
phyint igb1 disable
phyint igb2 disable
phyint igb3 disable
phyint igb1.10 enable
phyint igb1.20 disable

--------------------------------- (*,*,G) ------------------------------------
Number of Groups: 0
Number of Cache MIRRORs: 0
------------------------------------------------------------------------------

The log above clearly shows some traffic where 192.168.10.13-17 are Sonos speakers and 192.168.40.10 is my Android phone with Sonos control app trying to find them. I still get "We can't connect to Sonos". And somehow Multicast Routing Table is empty anyway.

Any ideas? Thanks!

@denix I will try to look into it this weekend, btw the tagging should not matter, tagging is only there in the trunk and when it leaves the subnet, so LAN or VLAN should not matter.
I don't know why you used "enable" in the config file, as by default all interfaces are enabled and as you can see in my config I disabled all but the subnet that holds the Sonos speakers and the other subnet that holds the Sonos applications.

@Qinn how do you have your Sonos speakers connected to the network? Do you use Bridge or Boost? Do you connect them Wirelessly or with Ethernet cable?

Neither all Sonos devices connect to a AP, so by WiFi and there is no bridge or boost from Sonos. In total there are 3 Sonos Play:1, 1 Play:3 and a Sonos Connect:AMP. On this AP there are 5 SSIDs's each with it's own VLAN ID (so isolation) IP's are (as it is a AP) assigned by the DHCP server from pfSense.

[denix]

@Qinn did you have to re-pair Sonos and the controller once you got your network and pfSense setup?

Nothing seems to work on my end. Unfortunately I don't have WiFi that can do VLAN, so isolation is done on a switch. WiFi connects to one of the ports that gets tagged, so everything wireless goes to that VLAN. I had most of my Sonos speakers wired, so once I isolated their ports to another VLAN, they dutifully got new IPs from pfSense's DHCP server for that segment. Running PIMD between those VLAN segments and the controller doesn't see the speakers.

I even ended up resetting the controller, and one of the spare Sonos:1 speakers. I paired them up, but the speaker got onto the the WiFi SSID and the same VLAN as the controller. That works, but the speaker now sits on the WiFi VLAN and refuses to connect with a cable to go into own dedicated VLAN... Tried pairing a Bridge, but since it's wired, it can never get detected by the controller, since they are in separate VLANs. PIMD doesn't seem to help a bit.

Can't get it to work, no matter what I try. Any help would be greatly appreciated! Thanks.

@denix Could you draw the setup of your network?

[Rai80]

@denix Did you enable the "Allow packets with IP options to pass. Otherwise they are blocked by default. This is usually only seen with multicast traffic" rule in the advanced options in your Firewall rules?

[denix]

@Rai80 bingo!

That was it. Once I enabled that option in Firewall Rules for each VLAN segment configured in PIMD, I started seeing a lot more traffic in PIMD debug.

One more thing - all the above works with existing setup. Creating new Sonos network or adding new speakers doesn't work, as I read somewhere that pressing Play/Pause and Volume+ buttons doesn't get propagated between segments over multicast.

Since I already reset the controller, I needed one more step: I brought up a temporary WiFi SSID on the same VLAN as Sonos speakers, connect my Android phone to that WiFi and setup the Controller. After that, moving it back to the main WiFi SSID works and it still sees and controls speakers on a separate VLAN with PIMD running.

Now I'm happy. Thanks everyone for all the help!

PS. Would be nice to figure out how to setup new Sonos speakers w/o using the temporary SSID...

[Qinn]

Nice that it works, but then I have to adapt the how to, as I explicitly mentioned that "allow IP options" was not needed and I can confirm that here I don't need to allow it, but my Sonos applications are not running on Andriod. Well, personally I don't understand why this is needed be that as it may, but the proof is in the pudding.

I added a second note to file.

Note 2: below is reported that on Android devices "Allow IP options" in the Advanced Options of the firewall rules is needed to enable to make it work, so if you don't have success, please try to enable it.

@denix now that it is working, can you confirm that when you quit PIMD, you can still connect to the Sonos speakers?

[denix]

@Qinn yes, seems to be still working w/o PIMD running.

I also need to lock down the firewall between VLANs - currently I have those completely open to each other. Need to close and punch holes according to this list:

@denix That was my conclusion also, thanks you have tested it, it seems that the applications save the addresses of the Sonos speaker for unicast, it's been 3 months that PIMD has been running and I can still access the speakers.

I'm at a loss... I think my issue is related to the TTL being set as 1 coming from the device sending the SSPD multicast. PIMD is setup exactly how you have it above and I'm still not seeing the traffic get through.

Does anyone know if there is a way to change the TTL for this type of traffic?

Why do think this and what does a debug or log show?

[alexbond93]

I tried to follow your guide (which is very clear and detailed), but I can't get it to work (not seeing any traffic).

Do you think it could be related to this https://forum.netgate.com/topic/140596/multicast-routing (TL;DR No IPv4 MROUTING kernel support.)?

[Qinn]

@alexbond93 can you see pimd is running and config it so that, the interfaces carreing the vlan's containing speakers and the one containing Sonos software, are not disabled? Btw did you take a look at the remark @denix Apr 2, 2019, 12:57 AM I personally not needed it, but it seems to help him?

[spaceboy]

unfortunately i couldn't get this to work. from my pfsense i have a wired vlan to a wireless AP to which all IOT including Sonos speakers are attached. main LAN VLAN goes to a unifi edgeswitch and then onto all other devices either wired or through another wireless AP.

i got pimd installed and configured it just to disable the WAN interface. i could see pimd in top but couldnt ever get the Sonos speakers to show up in the Sonos app on a pc on LAN.

i didn't set anything related to ip settings on the firewall rules as suggested. my guess is its something in the edge switch blocking it but i've given up for now. hopefully Sonos fix this in a future update

If TTL is set to 1 it's because the packet is not intended to be routed. This is often the case with multicast. So, when that packet tries to go through a router, the TTL will decrement to 0 and the packet discarded.

[chpalmer]

Thanks for the work here everyone!

I have a couple of cases where I need to traverse multiple routers with multicast. There might be a way to use pfsense for this after all. Right now its Cisco.

Think simulcast audio. https://www.gatesair.com/products/transport/public-safety-govt-communications

There are at least a couple other systems in the radio world that utilize multicast across subnets to distribute ROIP.
