Can't connect to UT3 LAN Server

[Asmodan]

Hi all, i've got a strange problem i can't solve myself:
I can see my UT3 Server in the LAN browser, but i can't connect -

my System:
Gentoo (vanilla) 2.6.23.9

CPU: AMD Athlon(TM) XP 2000+
1 GB Ram, 120 GB HDD SATA

I installed the server as user and use start/stop script from this forums (working nice, as far as i can see).
I tried starting as root and as user, no difference.

My startup Line:
gameopt="server VCTF-Necropolis?Game=UTGameContent.UTVehicleCTFGame_Content?GameMode=3?MaxPlayers=10?MinPlayers=1?TimeLimit=20?GoalScore=10?ServerDescription=AsmodanServer?bIsDedicated=True?bUsesStats=False?ForceRespawn=1?bShouldAdvertise=True?PureServer=1?bIsLanMatch=True?bAllowJoinInProgress=True?bAllowInvites=True?AdminPassword=XXX -Login=XXX -Password=XXX -unattended -nohomedir"
