Yes, my idea was correct for tupac: VPN+NAT, connected to all servers except server.war2.ru.
The problem is:
server blocks all the ICMP packets except request and reply. Maybe your routing scheme uses icmp redirect some way? That will be blocked by the server.
That means your nat is not properly configured, so server has to send icmp redirect packets, that helps to fix your routing.
Server.war2.ru doesn't send icmp redirect, i don't plan to allow that packets, so make sure your routes on NAT are proper.
If problem happened after entering login/pass, it could be related with UDP traffic.

FIXED THE PROBLEM. NEED TO SET MCU OF VPN CONNECTION TO 1500!

Nice now I can spawn free vpns with open ports that will work on ru. I will test this later!

I expect MCUs to be set to 1500 by default on any connection, but I don't use a vpn, so ok.

-- EDIT

Just out of interest, what was it set to before you changed it?

Wow! I ddn't think about that!
Looks like my firewall drops fragmented packets, good solution!
