configure pppoe on 831 router with modem in bridge mode

Hi,

Can some one please provide a config to setup PPPoE on the cisco 831 router to be used with a modem in bridge mode. I have tired other peoples configs found on the web but, not all the commands were available on the IOS version thats on the router. Also note that I bought this as a used router and I dont have a service contract so I am unable to download an updated IOS. The router ver is 12.3(7)T9 and the IOS is c831-k9o3sy6-mz.123-7.T9.bin. Running config below is last tried still could not connect or get ip address from isp. Wasent sure which ppp authentication to use so I used both pap and chap not sure if thats ok. Any help would be apreciated thanks...

configure pppoe on 831 router with modem in bridge mode

Hi,

you must put dialer 1 as nat outside interface and also change your nat statement like this:

no ip nat inside source list nat_address interface Ethernet1 overload

ip nat inside source list 10 interface dialer1

no ip access-list standard nat_address

access-list 10 permit 192.168.2.0 0.0.0.63

Let us know if this solves your problem.

Regards.

Alain
