Level 1

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...

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

Hi Alan, didnt make any difference. Is there a simple config even with out nat just to connect to isp using pppoe on router conected to modem in bridge mode? I can do the nat part later, just want to connect for now, I remeber seeing some one do that on youtube a while ago
