From: E-Double on
Is there some way to disable routing on a multihomed WinXP, sp3 machine ?
There is a multihomed WinXP machine that will act as as a proxy between two
seperate networks/subnets, but we want to ensure that the traffic from one
subnet can not access the other subnet through the PC (just PC's on each
subnet will be able to access that multihomed PC but not pass traffic through
it).

TIA ...
