I have a Win2K ISA box with 3 NICs, one is internet-facing and the others have IP numbers of 192.168.100.1 and 192.168.200.1. Right now machines in either subnet can get to the internet via ISA. I started to run RRAS to simply route between the two networks so they could "see" each other, but then I stopped - what is the proper procedure to bridge between the 2 internal networks while not lowering ISA's security?
