We are working with a school district interested in potecting both their Student network as well as the admin network.The two are totally separate(different subnets) except for sharing a switch for internet access. Is it possible for the two networks to share the same PIX? We need NAT translation, VPN capabilities to both networks. Do we to need to add another NIC into the PIX or do I need 2 PIX- 1 for each subnet.
