I have a router 1801, adsl port configured with one ISP, and Fastethernet0 port is configured with another ISP provider. So I want to configured like if adsl (ISP) not working then traffic pass through fastethernet0 (ISP)
I made commands:
ip route 0.0.0.0 0.0.0.0 Dialer0
ip route 0.0.0.0 0.0.0.0 FastEthernet0 10
ip nat inside source list 1 interface Dialer0 overload
!
access-list 1 remark INSIDE_IF=Vlan1
access-list 1 remark SDM_ACL Category=2
access-list 1 permit 192.168.2.0 0.0.0.255
dialer-list 1 protocol ip permit
But the traffic is not passing on Fastethernet0. Anyone can help me please. I also attached txt file

Hi,
You want to use adsl link as the primary path and the ethernet0 as backup, correct? Base on your configuraion, I think your NAT configure might cause problem. When your primary adsl link fail, the dialer wont have IP anymore hence the PAT wont work.
