Using Cisco Router (1941) To Replace Sky Fibre Router

[DRCB]

So after a bit of playing around (and this is likely more a Cisco IOS question), I have managed to get my Cisco 1941 ISR to make a trunk to the SKY cabinet.

I am showing an active line, and can ping the outside from the router, however client machines inside are unable to hit the internet end, I'm a beginner at these things with a lucky supply of various kit (Yes I know a 1941 ISR is a bit extreme, but its the smallest thing we had for me to play with!).

So...

I've got the VDSL connection connection up and running over RJ11 dsl, all good:

So from that side, all good. Except my client machines can't ping the internet. Internal IP's etc is all fine. They are getting DHCP provided gateways as the router and valid IP's (as said, internal routing is fine).

Anyone fancy a peek at this and seeing if they can spot anything blindingly obvious I have missed on the NAT side or the like?

Answered my own question! NAT was pointing at the physical interface rather than the trunk

All good now

[det]

No IPv6?

[DRCB]

Yeh... not figured that out yet!

[forevergroup]

lol clearly a Cisco question rather than a Sky one

Glad you got it sorted
