Hi Chris,
First, put two NICs in the firewall. That gives you some control, even
if both networks are on the LAT.
You don't need to guess which hosts have Welchia. Just run netmon on the
internal interfaces and the IP addresses will show up right away.
HTH,

if I have a:
network A ----> ISA server ------> network B
and network A and network B are each plugged into one nic on the ISA
server
can I block ARPs between the two? Any ideas on rules?
Both net a and net b are internal but one has Welchia virus and is
flooding
the net. Until we can find it and kill it we need to segment it off . .
