Is it possible to configure on NMB 3.7 to NAT outbound traffic to 2
public ip addresses based on internal subnet? We have two circuits to
our ISP - one T1 and one frame relay. The frame relay is configured
with a lower priority which makes it a backup if the T1 fails. We could
use the frame relay circuit for inbound traffic if we did the following.
Split our public class C network into 2 /25's and dynamic NAT some
internal subnets to public x.x.x.1 and some to public x.x.x.128. Route
return traffic which originated from public x.x.x.1 over the T1 and
traffic which originated from public x.x.x.128 over the frame. I think
the Cisco PIX lets you do this.
