[c-nsp] NAT on one interface

[Michael Malitsky]

Hello,

I am trying to figure out if it's possible to configure NAT in IOS on
just one interface.  Specifically, say I need to translate traffic flows
between X.X.X.X and Y.Y.Y.Y.  Y.Y.Y.Y is reachable through one
interface, that's my gateway to the "other" network.  However, X.X.X.X
can be reached through multiple interfaces.  Normal NAT configuration
requires me to specify a "nat inside" and a "nat outside" interfaces.  I
can certainly specify the gateway interface to Y.Y.Y.Y as "nat outside",
but I don't want to set a bunch of other interfaces as "nat inside" (nor
do I want to involve them in NAT processing at all).  Is there any other
way?

Thanks,
Michael Malitsky
