Has anyone created a bridging firewall using microsoft ISA server? Can this be done? I've managed to get this going (both as a transparent firewall and as a non-transparent firewall) under linux / open/freeBSD variants before, but never tried under Microsoft's solution.
The reason for wanting this is to be able to split an existing LAN in two without having to change (too much) of the existing infrastructure.
I'm 90% positive that I'm going to have to create to logical networks and route between the two to accomplish this properly, but would like to know if it's possible to simply use a bridge functionality instead.
