Re: Cisco 1841 Link to this post

Cool, can you post a config snippet on how you got it working and i will add it to the example config pages?

Re: Cisco 1841 Link to this post

All I did was add the config lines from the 837 example.

Didn't need to change a thing.

If you're building an example config could we look at some RPF, bogon, ACL and QoS suggestions?

eg

int Dialer0
ipv6 verify unicast reverse-path

int fa0/0
ipv6 verify unicast reverse-path

make the world a better place and all that =)

Re: Cisco 1841 Link to this post

Yep, good call.

Post up a recommended config if you feel like it, I may get around to it at some stage, but im a bit busy making it work at this end at the mo...

Cheers,
Callum
