The dhcp process doesn't interfere with nat.

in this answer i'll be assuming that you want to overload the inside addresses.

1st: configure access-list for your "inside"

access-list 1 permit

2nd: configure the global nat statement:

ip nat inside source list 1 interface f0/0 overload

i hope this helps

thanks for your help, I'm really confused but starting to understand this. How would I go about testing this when all I have is 2 2621xm and a laptop?

laptop --> with cross cable --> router f0/1.

then plug f0/0 with a cross to the other router.

I did this and was able to receive private dhcp but I don't get anything when doing "sh ip nat translations" on the router, is this correct?
