That must be a very special firewall.
Generally when you start IL-2 on Windows Vista / 7 / 8, the OS will ask you whether il2fb.exe should be allowed to establish connections to the internet.
Apparently you have to enable connections for all types of networks (home, work, public).
There is no need to completely disable your firewall, however you can do so for testing and if that solves your connection issues, please report back here so we can check your firewall settings.
I can see your connection attempts in the log Phas3e and I can see that something is going wrong, but I can't see the reason behind.
From the server's point of view it looks like this:
[2:51:40 AM] socket channel '131' start creating: aaa.bbb.ccc.d:51254
[2:51:40 AM] NetUser - Checking if user >Phas3e [aaa.bbb.ccc.d]< has any refly/KIA time penalties...
[2:51:40 AM] Chat: --- Phas3e joins the game.
[2:51:40 AM] socket channel '131', ip aaa.bbb.ccc.d:51254, Phas3e , is complete created
[2:51:41 AM] channel 131 DESTROY
[2:51:41 AM] socketConnection with aaa.bbb.ccc.d:51254 on channel 131 lost. Reason: Connection lost.
[2:51:41 AM] Chat: --- Phas3e has left the game.
A normal connect/disconnect looks like this:
[12:37:20 PM] socket channel '165' start creating: aa.bb.ccc.ddd:21000
[12:37:20 PM] NetUser - Checking if user >Storebror [aa.bb.ccc.ddd]< has any refly/KIA time penalties...
[12:37:20 PM] Chat: --- Storebror joins the game.
[12:37:20 PM] socket channel '165', ip aa.bb.ccc.ddd:21000, Storebror, is complete created
(...)
[12:41:38 PM] socketConnection with 46.59.247.168:21000 on channel 165 lost. Reason:
[12:41:38 PM] Chat: --- Storebror has left the game.
This line is what makes your attempts special:
[2:51:41 AM] channel 131 DESTROY
And the only thing that differs between your name and mine (or others) is that the log shows more empty space behind your name.
And that's the key:
You name ends with a tab.
That's not allowed, FBDj kicks you for that.
Please change your name, I guess the tab went in there accidentally, so just remove it and the connection will work.
