I do have wireguard on my server as well, I guess it’s similar to what tailscale does?
Too bad my friends from Russia can’t connect to me, it might be because we are doing something wrong, but most likely wiregueard is somehow (DPI?) blocked in Russia.
I can connect to my own wireguard, it routes all my traffic and I can access any blocked sites, as well as access other people via «local» IPs over wireguard. I think this uses NAT traversal and we exchange data directly over wireguard. But somehow some friens are not able to use that.
Do you know if Yggdrasil does something similar and if we exchange data directly when playing over Yggdrasil virtual IPv6 network?
