NAT - Translating all external source IP addresses to single inside address

I have an existing NAT setup using

"ip nat inside source list <x> interface <Outside IF> overload"

and

"ip nat outside source static <OutAddr> <InAddr>"

for outbound traffic, to:

1)Translate all inside source addresses to the outside interface address

2)Statically map outside addresses to inside local addresses 1 to 1.

What I need to do now is figure out a way to translate the source address of all traffic initiated on the outside, to a single address (could be the inside interface, or just any single address that I can setup routing to).

If there was such a command as

"ip nat outside source list <x> interface <Inside IF> overload" I think that would do it. But, alas, no such command.

I have been over the NAT options 'til I'm blue in the face. Anybody have any thoughts on this one?

Thanks!

Re: NAT - Translating all external source IP addresses to single

I have had the same problem. Unfortunately, many hours in the lab and I have been unable to find a way to PAT in both directions without a second router.
