Roy,

The router would already have a session in the NAT translation table so
it would know which global IP to use.

Subject: [c-nsp] Using NAT with servers and dual ISP

I have a customer with a connection to two ISPs and NAT.  I have 
outbound traffic working just fine with NAT route-maps and PBR

My consfusin is handling inbound connections to the customer servers.  I

can define inbound static mappings but how do the packets that the 
server sends in response make it way through the router and avoid going 
out the wrong interface.
