Or, slam another FE port into that Cisco and then let it handle all the
routing for you.  Just advertise another subnet to the two existing ones and
BAM!...you got game.... Then just pump all the traffic up your new pipe to
the ISA, al la:

Internet
...|
..isa
...|
...| <---(new subnet)
...|
..2600----(subnet1)
...|
...|
(Subnet2)

Default gateways on subnet1 and subnet2 stay the same so there just about
zero config and all your existing ACL's on the router would still be
valid....  All the coolness of an ISA protecting you, and a dedicated device
to do all your routing for you. Best of all worlds....

Troy, 

Thank you for your help. I have installed ISA at a previous job but it
only involved one network. Now I am working were there is 2. So I just
wanted to make sure this works before I purchase anything. 

Thank You

Dan

Then put the ISA on one network, then set your default gateways
properly. Or have the ISA on both networks and set up routing on that
and have it be the default gateway for everything.....

Yes, both networks go through a Cisco 2600 Router that has dual ethernet
ports

I am looking to install ISA but have one question. I have 2 networks.
One has IP of 10.8.100.? and the other 10.8.102.? I am wanting to know
if I can use 1 ISA server to be the firewall for both?

Thanks
