Hi, awesome WG mailinglist! My 18 year-old has recently moved out of home, and we're starting to yearn for one of our traditional Starcraft matches. I thought I should be able to do this easily with Wireguard. The idea, generally, is that one of us would start up a game, and Wireguard - with a side serving of ProxyARP and IP forwarding - would help make all the other computers see that game. (or, at very worst, allow me to run a game that could be seen by his computer AND the other computers here). -=-=-=-=-=-=-=-=-=-=-=-=- On his computer: (LAN IP 192.168.1.x) > [Interface] > PrivateKey = {blah}= > ListenPort = 12457 > Address = 192.168.88.3/24 > > [Peer] > PublicKey = {blah2}= > Endpoint = {my home}:12457 > AllowedIPs = 0.0.0.0/0 > On my computer: (LAN IP 192.168.88.x) > [Interface] > PrivateKey = {blah3}= > ListenPort = 12457 > Address = 192.168.88.2/32 > > [Peer] > PublicKey = {blah4}= > AllowedIPs = 192.168.88.3/32 -=-=-=-=-=-=-=-=-=-=-=-=- But it turns out not to be so easy. Starcraft sets up games over UDP 5353 and UDP 6112, and originally I thought it was a problem with forwarding UDP packets. However, I can see packets coming over the tunnel from his computer, but the packets are being forwarded to an address I don't know: > root@me:~# tcpdump -i home port 5353 or port 6112 > tcpdump: verbose output suppressed, use -v or -vv for full > protocol decode> listening on home, link-type RAW (Raw IP), capture size 262144 bytes > 20:02:35.744726 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10> 20:02:35.759142 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10> 20:02:35.759157 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10> 20:02:36.045323 IP 37.244.23.109.3478 > 192.168.88.3.6112: UDP, > length 19> 20:02:36.099993 IP 37.244.23.109.3478 > 192.168.88.3.6112: UDP, > length 19> 20:02:36.100005 IP 37.244.23.109.3478 > 192.168.88.3.6112: UDP, > length 19> 20:03:05.964077 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10> 20:03:05.964118 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10> 20:03:05.987761 IP 192.168.88.3.6112 > 37.244.23.109.3478: UDP, > length 10 Any ideas where I can start looking? I get similar behaviour whether I host the game on my computer or on his. Thanks in advance for any help you guys can offer!
