I wanted to do that once as well. And the problem is that you would need
to create subinterfaces on an Ethernet, one for ip Nat inside and one for
outside, --and the IOS will not let you create sub interfaces on a Ethernet
and then assign an IP address to them. If you try you will get the
following error message.

"Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10 or ISL vLAN."

Is it possible to do "NAT on a stick"? In certain circumstances I want to
have packets enter a router on the inside interface then have NAT applied
and send them back out on the same interface?

Any suggestions?

            Thanks, Darren
