Our ReVolt Pub

Some users of mine, still keep on having troubles with a very strange error.

We use Hamachi as vpn to play.
9 from 10 users play as on regular lan (as it could be).
But someone has this problem:
- he can see the created session (hosted game) as OPEN
- he can't see inside the session any player.
- if he tries to connect to the session, the system hangs for some secs (inside the net, i think) to a CAN'T CONNECT TO DIRECTPLAY SESSION error message.
- same equal error viceversa (changing the hosting & clienting)!!!

Now, we tried:
- disabling DIRECTPLAY protocol from multiplayer options (with BANDWIDTH option also activated)
- turning off any system security (firewall & peerguardian and so on), so there's only windows and hamachi running
- pathing revolt to 1207 exe

Testing DirectPlay chat session from DXDIAG gives positive check!
Pinging the unlucky client give positive response (also very low, about 70ms).
Tring a netbios connection to shared folders gives positive check!

What's up?
Seems some tcp packets to some ports were totally dropped

Any suggest is welcome!?!?!?!?
Thanxxx

The host must remember to set number of players from options to correct one (12 is maximum). If it's 8 only 8 can connect. This must be changed each time host starts.
