Hello! I might have found some explanation of the problem of disconnecting from the server after trying to log into the game. As I found about one of other games our beloved RKN cuts off UDP deliberately (corrupt it to be precise). Game server thinks that a client got internet connection problems and disconnects him from the server. RKN uses trash ICMP packets to make connection degraded and finally cause disconnect.
I don't understand much here. if this one is true could Warmane do something to help us to stay in the game without additional software? Something like trash packet filtering from russian's IPs or exceptions in firewall/cloudflare etc could help if those exist. The problem might have bound somehow with blocking services using Cloudflare. If Warmane uses concrete Cloudflare server and port you could reveal it so we would try to tune our zapret to bypass blocking. Not sure if this will help tho if the fact of corrupting of packets by RKN is real.
That decision above (zapret+warp) works but adds +30-80 of additional ping as well.
