how to configure NAT with multiple outside (due to backup)

[nicolasblain]

Hi,

I want to configure NAT for a customers with a ISDN Backup.

His primary link is on a Dial (PPPoE) and the secondary to (backup ISDN).

Do you know how to configure such a thing.

Thank you in advance.

ip nat inside source route-map NAT-PPPoE interface overload

ip nat inside source route-map NAT-ISDN interface overload
