Using multiple outside interface with ip nat overload

Hello,

I am trying to figure out if it is possible to use more than one external
interface with ip nat overload.

This ist not the complete config, just a sample with the most inportant
configuration tasks.

eth0
10.0.0.1 255.255.255.0
ip nat inside

bri0
encapsulation ppp
dialer pool-member 1
dialer pool-member 2

dialer1
ip address negotiated
ip nat outside
dialer pool 1
encapsulation ppp

dialer2
ip address negotiated
ip nat outside
dialer pool 2
encapsulation ppp

ip nat inside source list 101 dialer1 overload
ip nat inside source list 102 dialer2 overload

access-list 101 permit ip any any
access-list 101 permit icmp any any
access-list 102 permit ip any any
access-list 102 permit icmp any any

ip route 172.16.1.0 255.255.255.0 Dialer1
ip route 172.16.2.0 255.255.255.0 Dialer2


I tried it with a 800 and a 2500 cisco router with IOS 12.07 (T) without any
success.
If I have just one overload interface everything works fine, but I need to
have two of them.

Once again, I have 1x Eth and 1x BRI interface and want to use two
overloaded Dialer.

Thanks in advance,

bye

Try this:

access-list 101 permit ip any 172.16.1.0 0.0.0.255
access-list 101 permit icmp any 172.16.1.0 0.0.0.255
access-list 102 permit ip any 172.16.2.0 0.0.0.255
access-list 102 permit icmp any 172.16.2.0 0.0.0.255

ip route 172.16.1.0 255.255.255.0 Dialer1
ip route 172.16.2.0 255.255.255.0 Dialer2
