NAT/PAT + Internet connection

Hi everyone,

Here is my problem :

I've 3 routers (2600 series) :

They're connected like that by serial link : A \\ B --- Internet / C

Networks on routers A and B must have access on the net

I've configured a NAT Pool on router B with an access list :

ip nat pool internet 212.180.22.62 212.180.22.66 netmask 255.255.255.128 ip nat inside source list 2 pool internet overload

interface atm0 ... ip nat outside ...

all others interfaces (serials + ethernet) have ip nat inside directive

I wonder whether i have to add ip nat inside or rip nat ouside directive on the interface of my other routers (A and C)

Thanks Regards,
