NATing 2 outside interfaces to 1 inside

[KnowHope]

Hi Guys,

I have the following situation:

1 ATM interface with multi pppoe connections over 1 pvc.
I use Dialer 1 for ISP1 and Dialer 2 for ISP2.

Currently Dialer 1 is functioning correctly as nat outside and Ethernet0 as nat inside, I wish to nat Dialer 2 with the same subnet that is on Ethernet 0.

Is there a way to do it?

Appreciate any thoughts around this
