How can I get this UDP relay package for casting across VLANs?
-
I expect either:
/usr/bin/nohup /root/udpbroadcastrelay/./udpbroadcastrelay --id 1 --port 5353 --dev igb2.60 --dev igb1.70 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/nullOr don't bother with sending output anywhere and just use:
/usr/bin/nohup /root/udpbroadcastrelay/./udpbroadcastrelay --id 1 --port 5353 --dev igb2.60 --dev igb1.70 --multicast 224.0.0.251 -s 1.1.1.1 -fBut try killing the process after it boots. The other services will then start if that is what you're hitting.

I actually tried the second command you provided first, as I don't really need the output and it hung the services. As you suggested, killing it then allowed the services to start.
I tried one last time with the first command - and it looks like it may have worked! I'm not going to get another chance to reboot for a bit to test again, but I am optimistic enough to say thank you for your help with this. I'm not sure why it was hanging it, but it seems this approach may have addressed it.
-
I snuck in a reboot while I had a moment and I can confirm it is working with the first command you provided. Thanks again, Steve.

Nice!
Let us know how that goes. You might open a feature request in redmine to create a package for it if it performs well.

@stephenw10 It's still going great, and I submitted the request:

Hi all,
This is an interesting thread - I had a couple questions:
-
Any particular reason 1.1.1.1 is used as the source IP instead of an IP address on the subnet that contains the chromecasts?
-
Can the UDP broadcast relay code also be compiled on pfSense or is a separate install of FreeBSD 11.3 required?
Thanks in advance.
-
-
Unclear why 1.1.1.1 is used there. It could just be an example IP.
Yes you need a separate FreeBSD install to compile it. There are no build tools in pfSense.

Thanks @stephenw10 ! Regarding 1.1.1.1, looks like it's all explained here (should have read a bit closer):
https://github.com/marjohn56/udpbroadcastrelay#udp-broadcast-relay-for-linux--freebsd--pfsense--opnsense
I just wish they had used a different address than 1.1.1.1 since that's also the IP of Cloudflare's DNS -- makes it a bit confusing.
Once the code has been compiled, is there a recommended location (directory) to put the binary on pfSense?
Thanks again!
-
Ah, yes. Special IP. I agree, that's not a great choice. You can change that in the code, probably easier to live with it though.
You can put the binary anywhere in the path. I would probably put it in /root at least initially so it doesn't get overwritten.

Just wanted to follow up quick and validate that this works great! Compiled the code to binary on FreeBSD 11.3, moved it over to pfSense, and then used the command from Steve above to autostart it using ShellCmd (replacing dev devices as needed with my own):
/usr/bin/nohup /root/udpbroadcastrelay/./udpbroadcastrelay --id 1 --port 5353 --dev igb2.60 --dev igb1.70 --multicast 224.0.0.251 -s 1.1.1.1 -f > /dev/nullEverything starts up fine after a firewall reboot and Google Home (Casting) and Apple TV (Airplay) work without issues. Avahi is no longer needed, plus there's the added bonus that Google Home speaker groups now work properly if the mobile device is in a different network subnet as the speakers / chromecasts.
Thanks again guys! Hopefully this can be made into an official pfSense package soon.

Nice!

@tman222 @stephenw10 Yeah, it's awesome. Glad you figured it out. I was planning to respond to you but I just saw your messages as I was going into some work meetings.

Aaannnd......now it isn't working. It's odd, because I didn't change anything that I can see would affect this. I was tweaking a couple of DNS settings (not mDNS) and I noticed it shortly after, but even putting them back and checking that the relay is running it is no longer showing my groups in the other VLAN. I had stopped avahi because as you noted it was working fine without it, but even turning that back on hasn't fixed the issue. I'm not sure why it stopped, though there was an update to the Google Home app recently....
-
Actually that must be part of the issue. I just looked and the groups are still showing on my iPad, just not on my Android phone at the moment. Grrrr.....
UPDATE - Nah, they show up but can't cast to those groups any longer unless I connect to that VLAN.
-
Hi @burntoc - everything is still working fine here. I just checked on an iPhone and it does have the latest version of the Google Home app installed. What changes did you make to DNS? Also have you tried resetting your firewall states to see if that helps (i.e. forcing all the connections to be reestablished)? Come to think of it, I did have a bit of trouble the other night after I created a new group and then couldn't cast to it. However, after a few more attempts it did eventually start working and has worked fine since.

Just wanted to follow up on my last post real quick to confirm that everything is working is still working fine on Android based device as well for me (using latest version of Google Home app).
@burntoc - were you ever able to resolve the issues you were seeing?
-
@tman222 Thanks for following up - and confirming that your Android GH app is working okay. Mine is still not working well, though I've noticed that Home isn't working great in general atm (e.g. I ask it to play streams and they time out more often than not). I have one Google Home Hub in the IOT VLAN with my Chromecast audios, Google Home speakers, etc. and I wonder if something about the multicast address registration is not working properly. I've rebooted the firewall and the Google Home Hub but still no joy here. I'm pretty certain here weren't any other changes to my network. I have a couple of other things I probably have to prioritize above further troubleshooting, but worst case I'm planning on some troubleshooting no later than this weekend.

@burntoc - did you change any settings on your wireless access points or network switches?
-
@tman222 That's what I'm going to check, but I'm 99% sure I did not change any of that. I have 2 APs that trunk to the main switch, and I didn't mess with those APs, the trunks to the switch, or the trunk from the switch to the fireawall. No other mDNS or other changes, either.
-
Just wanted to follow up on this thread quick and mention that this is still tool is working great for me without any issues (despite several reboots of the firewall since the initial install and configuration). A great alternative to Avahi if one is looking to get Google Home speaker groups to work. Even though I have not been able to try this out yet, it may also be a suitable alternative for pimd to get Sonos speakers to work.
