Default Add a subnet with a Pix firewall


Hello,
I'm encountering the following problem ...
The 64 IPs address subnet assigned to my LAN is now full and I need to
add more computers in the same LAN. I've got a second subnet available
but not in the same class C ...
The first subnet is behind a Pix Firewall on the first interface ...
How can I can configure the Pix to protect the second subnet and make it
communicate with the first subnet ?
Thanks ...
Michel

You could put a router in behind the pix on the first subnet with one
interface in the second subnet. Put routes in on the router and the pix and
point all the clients at the router on the second subnet for their default
gateway. Add NAT rules for the second subnet on the pix and away you go!

Chris.
