Ras server Slip & PPP options for game play by modem 56k

Hi all,
I maked an incoming connection with a modem 56k for game play with a my
friend on Unreal Tournament. Maximum speed connection is 33.6K (and I
know why). Because UT is a FPS game, it require lowest ping & latency
possible. I have tried many options by client side (my friend) and I was
unable to go under 100 ms for the ping. I hope to reach 80-90 ms.

Settings of client side are:

Modem Options: Error flow control HW activated, Error control &
compression HW deactivated, 115200 bps.

Net options: PPP -> LCP extension activated, software compression
activated, multipoint deactivated. TCP/IP: Header compression activated,
NetBios over tcp disabled.

I use sygate firewall for blocking unneeded packets (svchost, ntoskrnl
and more) whether on client side that hos side.


In incoming connection tabs, there aren't any kind of option for
optimize connection such as PPP header settings, compression, etc.
Anyone have some idea?

I found on internet that slip protocol is very suitable for my purpose
(It's light) but in ms technet have found that is impossible activate it
on incoming connection. Are there software regards it?

Help me, thanks in advance, bye
