thank you so much for the replies guys! i'll try it out and let you know if it worked!

UPD: okay, the DMZ thing helped with making "4-mans" room visible, and that is enough for me atm, so thanks a lot!

On the other hand, server manager seems a bit more difficult. I downloaded original server manager, added files from the folder you sent and when trying to start server, it gives an error - "couldn't write server rotation file"

Hey guys! i'm new to the community and to the games, but i managed them both to work properly online on my PS2, but the only thing i don't get and couldn't find answer anywhere - is it possible to host rooms using DNS that work at the moment? Because dedicated servers have large ping for my place and also i'd like to play with my friends, so we could pick maps etc, not just play what's given. I know there's an option "create", but the created room doesn't seem to be visible in the lobby.
So I would be very thankful if you could help and explain, is it possible in any way? (maybe even changing DNS to smth else?)
Thanks in advance!
