How can I get this UDP relay package for casting across VLANs?

Oh that's interesting, I didn't realise it had been included upstream. Makes things a lot easier.
Though I had to upload it rather than fetch it directly:

Cool, this is great news! I assume this link is for the amd64 version of the package?
https://pkgs.org/download/udpbroadcastrelay
https://freebsd.pkgs.org/12/freebsd-amd64/udpbroadcastrelay-0.3.b.txz.htmlI actually just recently recompiled the udpbroadcastrelay source for pfSense 2.5.0 (FreeBSD 12.2 Stable) but will keep this link in mind for future versions. I'll also update my initial post in the thread above.

@stephenw10 - when installing the
udpbroadcastrelayas a FreeBSD package, where on the file system is the binary located (will be needed for ShellCmd)? Thanks in advance. -

@stephenw10 - when installing the

/usr/local/binand configuration files in/usr/local/etc. Any shell script provided with the package typically winds up in/usr/local/etc/rc.d. But these are not hard and fast rules - a package creator might deviate from the standard practice. -

btw if you don't have the repository, then do a
pkg add https://pkg.freebsd.org/FreeBSD:12:amd64/quarterly/All/udpbroadcastrelay-0.3.b.txzfor an AMD64 and then a
rehashand a
pkg info udpbroadcastrelayshows it is nicely installed

Hi,
can someone give me a hint how the command looks like for Shellcmd/command prompt (pfsense 2.5.0 / APU2C4)?
With "find / -name 'udpbroadcastrelay'" I could find udpbroadcastrelay in "/usr/local/sbin/".
With Putty and "/usr/local/sbin/udpbroadcastrelay --id 1 --port 5353 --dev igb1 --dev igb1.12 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/null" everything works perfectly but not in pfSene (command prompt) itself. -

/usr/bin/nohupcommand as part of the ShellCmd: -
Hi tman222,
thank you very much!
I read your post, but I thought it would also work with "/usr/local/sbin" instead of "/root/udpbroadcastrelay/". Now I copied "udpbroadcastrelay" to root... and it works like a charm

Hi @Itar - I would have expected it to work from
/usr/local/sbinas well as long as you have the/usr/local/nohupand call the executable by./udpbroadcastrelayif needed (note the./) The instructions above are bit dated back from when we had to compile the code manually to create the binary vs. installing it as a FreeBSD package. -
Hi tman222,
no, I tried /usr/bin/nohup /usr/local/sbin/udpbroadcastrelay/./udpbroadcastrelay --id 1 --port 5353 --dev igb0 --dev igb1 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/null but it didn't work.

Hmmm - do either of these work?
/usr/bin/nohup /usr/local/sbin/./udpbroadcastrelay --id 1 --port 5353 --dev igb0 --dev igb1 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/nullor
/usr/bin/nohup /usr/local/sbin/udpbroadcastrelay --id 1 --port 5353 --dev igb0 --dev igb1 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/null -
Ahhhhh,
/usr/bin/nohup /usr/local/sbin/udpbroadcastrelay --id 1 --port 5353 --dev igb0 --dev igb1 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/null
is working!
Thanks!

Re: How can I get this UDP relay package for casting across VLANs?
So I just came across this thread after trying for over a day to get Sonos clients on my LAN subnet discovering the Sonos devices on an isolated IOT subnet using the PIMD package as a multicast reflector.
IOS clients that had previously been connected when everything was on the same subnet continue to work once the relevant firewall rules were setup, but new clients (Mac, Win10) can't discover the Sonos device.
I've removed PIMD, rebooted and installed the package as per the instructions above. I'm seeing the following error when trying to run the command (as root) with the debug option:
# udpbroadcastrelay --id 1 --port 1900 --dev igb1 --dev igb2 --multicast 239.255.255.250 -d ID set to 1 Port set to 1900 ID: 1 (DSCP: 1, ToS: 0x04), Port 1900 igb1: 2 / 172.16.10.1 / 172.16.10.255 igb2: 3 / 172.16.20.1 / 172.16.20.255 found 2 interfaces total IP_ADD_MEMBERSHIP: 172.16.10.1 239.255.255.250 IP_ADD_MEMBERSHIP: 172.16.20.1 239.255.255.250 bind: Address already in use rcv bindNot sure what would already be using 239.255.255.250:1900 or how to go about debugging from here.
Any pointers greatly appreciated
-
did you do a ps to check if it is already running?
-
There are no other instances of udpbroadcastrelay running but pfTop shows an existing state from the pfsense interface on the IOT subnet.
pfTop: Up State 1-1/1 (545), View: default, Order: bytes PR DIR SRC DEST STATE AGE EXP PKTS BYTES udp Out 172.16.20.1:52980 239.255.255.250:1900 SINGLE:NO_TRAFFIC 00:02:52 00:00:09 132 62676I'll try temporarily powering down all other devices on that subnet and see if that helps
-
The way to check if it running and to stop udpbroadcastrelay is using the ps command and kill the process using it's process number (PID)

@captaincathode Would be good to disable other related plugins and/or other firewall rules on you IoT subnet like Avahi etc if you ever had them installled.

Anyone here using HomeKit across VLAN’s? I have Apple’s Home app successfully work to recognise and control many devices on my IoT VLAN’s.
One minor annoyance I have been having is with a particular smart home device - Meross Garage opener (HomeKit version). Their mobile app works fine over VLAN’s, however via the native Apple Home app(& via Siri) I’m unable to open the garage on the first request (even though the app acknowledges that the request has been successfully completed). The subsequent call / 2nd request always works like a charm and the garage opens up consistently. This means my garage door automations don’t work as expected via the Shortcuts or Home App.
I’m wondering if that’s due to the nature of VLAN hops and how that specific device works across VLAN’s? Or some other issue related to HomeKit or the Home App on iOS itself? FWIW, I have plenty of other IoT devices(eg Light Bulbs, Sonos speakers etc) connected via HomeBridge all of which work fine (mostly :-)) on the first attempt.

Getting back to this after nearly two weeks of being too busy to look at it . . .
I found that UPnP/NAT-PMP was preventing udpbroadcastrelay from starting. I have an XBox One on the same IOT subnet, and pfSense is configured to allow it to use UPnP.
If I stop the UpNP/NAT-PMP daemon (miniupnpd) I can successfully start udpbroadcastrelay and my Sonos controller can now see the devices across subnets.
udpbroadcastrelay --id 1 --port 1900 --dev igb1 --dev igb2 --multicast 239.255.255.250 -dOf course then I can't start miniupnpd again until the udpbroadcastrelay process is killed, so it seems the two are mutually exclusive, or at least when both are trying to use UDP 1900 (SSDP) on multicast address (239.255.255.250).
Other than moving the XBox or Sonos devices into their own VLAN, I can't see a workable solution here, but admittedly my IPv4 multicast knowledge is pretty basic.
Any further suggestions welcomed.
-
Yes, you can't have two processes listening on the same port like that. You can either relay the SSDP packets or accept and use them with UPnP. Or be more secure and do neither.
