Can access plex via my IOT vlan but not my inhouse vlan.

@Nath2125 well you sent a syn and never got an answer - so you yeah it was closed by the client. If you get no answer - but other vlans can access it - that would point that 10.4 box not allowing it.

I would sniff on the 10.4 interface - allow ping, and ping the 10.4 from your 31.12 do you see the pings being sent on to 10.4, any answers? If not then its not getting to your plex or its not answer, or sending the answer to something else? Or you blocking it via a floating on the outbound side?

Nath2125 · Jun 16, 2023, 1:18 PM

@johnpoz when you say sniff the interface and allow ping. What do you mean by that? Do you mean go to the ping option and try and ping or setup another firewall rule to try and ping. Little confused sorry.

I shouldn't be blocking anything in floating rules in regards to your last comment.

@Nath2125

here - I am pinging and doing a packet capture on pfsense.. see the ping request go out, I get a response.. What does yours show?

I am doing a packet capture on my lan interface, where my 9.10 box sits - and pinging from my phone on the 192.168.2 network - it is routed through pfsense and pfsense sends it on, see the ping request.. Then my box answers, the reply..

If you see the request go out, but no reply then something on your box your pinging is not answering, or its sending it somewhere else - or something is happening to it after pfsense puts it on the wire and that what your pining never got it.

@johnpoz Ok so i ran this with these settings. The perslan is where plex sits on the 192.168.10.4 as well as pfsense sitting on the same subnet lan network. I put in the 192.168.31.12 address which is my iphone trying to connect to plex with and put the capture below. I should add also the 192.168.10.5 is my pihole dns

@Nath2125 and nothing in there is showing any response at all..

Doh.. here is a response

23:48:00.979978 IP 192.168.31.12.50683 > 192.168.10.5.53: UDP, length 42

But I see no responses to your 32400.. Prob be easier if you say filtered on IP and port..

if your sniffing on the pfsense 192.168.10 interface - you can see pfsense is sending on traffic to 10.4 from 31.12 to 32400, but there are no responses.

Nath2125 · Jun 16, 2023, 2:12 PM

@johnpoz did the same again from settings above except now with port 32400 filtering. I run this while trying plex from that ip.

Yes the 192.168.10 is the interface i have selected (perslan)

@Nath2125 well so either plex is not running? Or you have a firewall on that host? Or that server is sending its response somewhere else..

here fired up a connection from my phone on the 192.168.2 network to my plex 192.168.9.10 doing a sniff on the 192.168.9 interface on pfsense. You can see it sends on the trafic from 2.198 to 9.10:32400 and there is a response sent back that pfsense sees.

login-to-view

If you see pfsense send on the traffic - then you know your firewall rules allow the traffic.. But pfsense has no control if the device is going to answer.

@johnpoz I can see what you mean by it sending it back. I can assure you plex is running and no seperate firewall is running. I run simply pfsense with omada gear switch and AP's and everything works fine on the other vlans i have running. Here below is a capture from the IOT vlan i have (192.168.40.x) and it looks to be responding back. So im still quite confused whats causing this.

@Nath2125 well your going to have to look elsewhere pfsense is clearly sending it on.. I would do a sanity check that pfsense has the correct mac address for your plex as a place to start..

[23.05-RELEASE][admin@sg4860.local.lan]/root: arp -a | grep 192.168.9.10
i9-win.local.lan (192.168.9.100) at b0:4f:13:0b:fd:16 on igb0 expires in 725 seconds [ethernet]
nas.local.lan (192.168.9.10) at 00:11:32:7b:29:7d on igb0 expires in 294 seconds [ethernet]
[23.05-RELEASE][admin@sg4860.local.lan]/root:

Then if I look on my nas where plex is running

ovs_eth0  Link encap:Ethernet  HWaddr 00:11:32:7B:29:7D  
          inet addr:192.168.9.10  Bcast:192.168.9.255  Mask:255.255.255.0

Might want to sniff on your plex box and make sure the traffic is getting there.. We know pfsense is sending it - but are we sure its getting there?

So for example here I am sniffing on my nas were my plex is running.

@johnpoz I've looked into mac addressing and looks to be fine and matching. I don't know why its not responding back like the other vlans are. I just unraid with Plex and having changed network settings since they always used to work. But I'm unsure now. IL keep thinking about other possibility of what I can do.

Reading through those packet captures looks to be just my unraid server not responding on that IP address, although responds fine to the other vlans. I really can't see what's making this different from the others.

@Nath2125 possible mask problem.. I didn't look to what the other networks are.. But one thing that comes to mind where answers to some source IPs work and others don't - other than a firewall blocking access from source, or only allowing specific source would be a mask problem.

Where source IP X comes in and the plex thinks oh that is on my local network, do you have a mask other than /24 ? If the plex box thinks the source IP trying to talk to it is local to its own network it would never send answer back to its gateway (pfsense).

If you sniff on your plex box and see it come in, look to see if it arps for that IP right after, if its arping for it - it thinks its on the same local network. Or just look at the mask on the interface on your plex box.

Are you running plex as a docker, or just native.. Docker likes to do stuff behind a nat, etc.

Nath2125 · Jun 16, 2023, 3:11 PM

@johnpoz every IP range for every VLAN is /24. Plex is run on docker, which is an integration with the unraid os. So pretty much docker. Trying to figure out the best how to sniff my unraid box atm.

johnpoz · Jun 16, 2023, 3:32 PM

@Nath2125 can't you just ssh to your unraid or console in and install tcpdump?

edit: horrible work around, but as a quick fix until you figure out what is going on.. you could always source nat on pfsense so traffic from that network looks like its coming from that 192.168.10.x interface on pfsense - so now when you talk to plex from that network, plex would think its just some client on its own network.

Could it be something as stupid as routing.. what does your routing table look like on the unraid box, I would think just a default route to pfsense IP? Is that unraid box multihomed?

Nath2125 · Jun 16, 2023, 3:54 PM

@johnpoz what do you mean by multihomed sorry and yes its using the top default in the image which goes to the 192.168.10.1 which is pfsense.

Getting tcp dump on my unraid box atm.

johnpoz · Jun 16, 2023, 4:02 PM

@Nath2125 well this looks like a problem to me..

That 192.168.16.0/20 would include your 192.168.31 your trying to talk from..

192.168.16.0 - 192.168.31.255

Would be that network range - so yeah you have a mask/routing issue.. Where that box thinks to get to that 192.168.31.x address he should just use that br-2b99 whatever interface that is vs sending it to your default gateway 10.1

@johnpoz said in Can access plex via my IOT vlan but not my inhouse vlan.:

Ok so i changed the vlan to a 192.168.32.x subnet and it seems to now be picking it up. So you are correct. I did try and delete it and or find out how it was created in the route table on my unraid server but it for some reason wont delete and I dont know where it has come from so thats for further investigation. But for now its picking up fine when i moved it out of the 192.168.16.0/20 range.

johnpoz · Jun 18, 2023, 1:34 PM

@Nath2125 I believe that 192.168.*.0/20 is a by design network - I think it tries to use networks that are not in use and then creates a network.. So I would guess for whatever reason, it didn't detect this network and picked 192.168.20/20 which causes your problem.

Simple fix is what you did and just use a different network outside that /20

Or you could dig into docker and have it use a different range that won't conflict with the other networks you want to use.
