We just got a second set of public IPs from our ISP. They own the T1 router, and configured it to use both subnets on the same ethernet interface. If I hang a switch off of the inside interface of the router and give machines (also attached to that switch) static addresses from both subnets, everything works fine. But now, in reality, we have the pix between the router and the switch. The outside interface of the pix is assigned an IP on the first subnet. If I create a static NAT using an address from the first subnet, all is good. If I create a static NAT using an address from the second subnet, traffic from the inside host doesn't make it past the PIX. What do I need to tell the PIX in order for it to know what to do with traffic NATted to that second subnet?
