I am configuring a cisco 3550 switch with several vlans for my network. I would like to nat 1 of the fa ports to a different subnet since that port will host a connection to a trusted trading partner. Since that trading partner has the same subnet addressing scheme as I do, I need to nat to a different address group. I don't want to re-address my internal hosts so I am back to natting. Is this possible or do I have to insert a router in between?
My plan was to set up a vlan with and assign it to the interface that will be servicing the connection and then set up natting on that VLAN interface with several static nats.
