log 1: disconnect on jump

With london2038.com (http://www.hellgateaus.info/forum/server-reboot/) there is
a new server for running Hellgate London in multiplayer.

The windows people can play find.
The most things I can do to.
Like:
- connect to the server
- create and choose a character
- enter stations and tunnels
- chat
- talk to npcs
- walk around

So far so good.
But when I do certain actions I get disconnected.
Like jumping. When I jump, sometimes on the first jump, sometimes later.
Everytime I shoot when I'm in the dungeon (can't shoot in stations).

I tried first with wine-2.0-rc6, then staging.
Tried earlier versions.
Tried some winetricks dlls.
Now with wine-staging-2.0.

Also made a thread on there forum
(http://www.hellgateaus.info/forum/support/hgl-on-linux-with-wine/)

Funny part:
Tried on another PC. Same Debian 64bit. Same wine from repos.
First it disconnected like always.
Then, I don't know what I did, it stayed connected.
I tried to reproduce it but couldn't. Changed wine version. (Of-course always
deleting wine-prefix.) 
Nothing. It stayed connected (most times). While on the other machine it always
disconnects.
Tried same debian packages (probably just little different versions) on both
machines. Same /proc-net-TCP-settings.
No change.
Same network with via cable on same switch.
No change.

While staying connected I could see:
- doing nothing ping was around 150ms
- doing something the ping rose (saw times up around 100000ms...) until
standing and waiting, then it would fall normal again
- lots of tcp packages flowing in wireshark while actions were happening
Not really playable. But it stays connected. Somehow...

Now I made logs with
