Hi all

interface Serial0/0/0.2 point-to-point ip address 10.16.129.170 255.255.255.252 ip nat outside frame-relay class internet frame-relay interface-dlci 16

interface ATM0/1/0 no ip address no atm ilmi-keepalive dsl operating-mode auto pvc 8/35 encapsulation aal5mux ppp dialer dialer pool-member 2

Interesting question if I'm understanding it right:

You're asking if when interface A is up, if a static NAT can be in effect (ie IP 10.10.10.1 -> 5.5.5.5) but if interface A goes down and dialer B comes up, if that static NAT can change dynamically (ie IP

10.10.10.1 now -> 6.6.6.6).

I have no idea (I would think it would require more than static NAT's to accomplish this) but I would be interested if someone with more expertise could answer this definitively.
