Strange NAT Question

[admin_2]

Is there a way to have a inside interface with two IP address ( 10.25.0.1 and 10.18.0.1 ) do a static NAT between two inside hosts ( 10.25.0.100 -> 10.18.0.100 ) or do I have to have a second interaface? I want to be able to ping 10.25.0.10 and have 10.18.0.10 respond.

I am running 12.1,20 IP Plus 56.

May be you can use something like NAT on a stick to do NAT on the same interface.
