Quake 3 with cipe

Hi All,

Noticed a problem with Quake 3 network traffic when routed over cipe. 
Quake 3 sends four times as many UDP packets to the game server as it 
does when outside the tunnel (or in a ssh/pppd tunnel). This problem 
only happens when the Quake3 client runs on an XP machine, reboot into 
Linux and the packet rate becomes one-to-one.

This is still the case when the Linux Q3 config file is copied over the 
Q3 XP config. All in all, suggesting some sort of interaction problem 
with cipe and XP, but I've no idea what.  Does anybody have any suggestions?


Some background... Quake does most of its communications using UDP port 
27960. The game server sends packets out representing the current state 
of the game at a rate of around 25 per second, ~100 bytes each to port 
27960. The clients send back packets representing the users actions, at 
around the same rate, size and the same UPD port.

The machine layout consists of the 'game machine' - dual booting between 
XP and RedHat 7.3; a RedHat 7.3 firewall machine running cipe connected 
to the internet with adsl. The Q3 server and another cipe runs on a 
RedHat 9 machine directly connected to the internet.


Thanks,

Richard
