Thanks, that was what I was afraid the answer would be since the nat commands were not being accepted on the switch. Interesting that Cisco Level 3 support is telling me that it is supported, even after I pressed him to be sure.<br />

Thanks for your insight!

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? <br />
<br />
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.

CAN YOU NAT on a CISCO 3550 switch using a VLAN Interface?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
