Using NAT with CEF?

Hello all. I have a 7206VXR with two outbound (WAN) T1 interfaces. Traffic going out to the internet is load balanced through these two interfaces. There will be multiple LAN links coming into this router, all needing to be natted. My question is, if I am running NAT on this router - do I configure BOTH of these WAN interfaces with "ip nat outside"? I am assuming that BOTH WAN links need to be configured as the "outside interfaces". Is that correct?

CEF does not create a single "logical" interface for you to make configurations on, so I am assuming that you have to simply configure each CEF interface independently. Also, does using NAT have any affect on interfaces that have CEF enabled? Thanks in advance...
 
I answered my own question for those who were ever curious about this....


Stupid me, all I had to do was just build an IP pool (instead of pointing to a specific interface). Since I had a block of public IP addresses routed to BOTH interfaces through my ISP....I simply created a NAT pool.

Funny what people can do when they actually use their MINDS.....
