openvpn?

I have mt-daapd listening on 0.0.0.0:3689; I have my WiFi card on 10.0.30.0/24, and my OpenVPN server on 10.0.40.0/24. My Roku Soundbridge on 10.0.30.0/24 sees the mt-daapd server fine, and it also sees iTunes running on my laptop on 10.0.30.0/24. However, iTunes doesn’t see mt-daapd on 10.0.40.0/24. I have a firewall blocking all but the Soundbridge off 10.0.30.0/24, but since I have my laptop on 10.0.40.0/24 and absolutely no restrictions on the VPN network, why can’t I see the server in iTunes?

Because your vpn isn’t passing multicast traffic. You can make it do so, I believe — I’m pretty sure I saw some stuff on doing just that, but I believe it requires running some sort of extra routing stuff on the server end.

The other alternative is to run a mdns proxy on your side. There are a couple out there, check the FAQ page for tunneling over ssh. I realize that isn’t what you are doing, but the stuff on mdns proxying still holds.

this is one of those things that seems like black magic even after I get it working. I installed (with apt-get) pimd, added a couple lines in pimd.conf to keep it from working on my public-facing interface, then added a line to my shorewall rules file like this:

ACCEPT all vpnserver:224.0.0.251 udp 5353

Restart Shorewall, and BAM, i’m set. Thanks, but this could really do with a lot more documentation.

Well, here’s the documentation right here. 🙂
