OpenVPN update: no way to use the russian OpenVPN server... network latency too high. We are setting up a local server in Italy to try to use it for our test: news as soon as possible.
UPDATE: OpenVPN server seems to be not stable and reliable: no way to test the MOD. We will try another session using Hamachi.
UPDATE 25/8/2010: Hamachi test revealed same problems as direct native connection: usual problems on torpedo acquisition, apart for MK48, and rare CTD due to unknown problems, and strange sonars behaviour. Our feeling is that time conditions in doctrine files are affected by lags on network during multiplayer sessions, and the result is a mess in doctrine execution: this could be the reason for unexpected CTD due too too many time difference between client and server.
