This is now solved. My configuration was all correct, however I needed to put the PVC and encapsulation type etc under the ATM0.1 NOT ATM 0. The Cisco guide was wrong in this. Thanks to everyone who helped! ... View more

Hi Alain, I've set the router to defaults and gone through the entire setup again. The only differences to the guide you mentioned is that I used vlan75 instead of ethernet0/0 as the nat inside etc. The config is attached with the "show ip interface brief" command at the bottom too. Thanks again for persevering! ... View more

Hi Alain, As mentioned in my initial post, that is what I started with. I then basically only changed the DHCP range. I'll reset it all and start again if you wish. Will post back with findings. ... View more

Hey there, Thanks very much for the detailed reply. Unfortunately it's still refusing to pickup an IP address.

I'm not sure whether the syntax for my ADSL connections is correct?

Not sure if you get alerts to replies to other's messages but I've tried your suggestion and unfortunately it didn't help fix the route issue (although was probably a step towards the right direction! Thanks for that ) Do you have any idea about the updated issue above? ... View more

Thanks for the help so far guys. I have changed a few things in my config, like removing the packet dropping and I've checked that the IP is being picked up by the dialer.. which it's not. Here is the output from my interfaces: show ip interface br Interface                  IP-Address      OK? Method Status                Protocol FastEthernet0              unassigned      YES unset  up                    up      FastEthernet1              unassigned      YES unset  up                    down    FastEthernet2              unassigned      YES unset  up                    down    FastEthernet3              unassigned      YES unset  up                    down    ATM0                       unassigned      YES DHCP   up                    up      ATM0.1                     unassigned      YES DHCP   up                    up      SSLVPN-VIF0                unassigned      NO  unset  up                    up      Vlan1                      unassigned      YES NVRAM  administratively down down    Vlan75                     192.168.1.1     YES NVRAM  up                    up      NVI0                       unassigned      YES unset  administratively down down    Dialer0                    unassigned      YES NVRAM  administratively down down    Dialer1                    unassigned      YES NVRAM  up                    up      Virtual-Access1            unassigned      YES unset  up                    up      Virtual-Access2            unassigned      YES unset  up                    down    As you can see, it's not getting an IP from the ISP. However, I'm not sure which part to try and fix! I understand that the ATM is the actual port I plug the ADSL cable into and the Dialer 1 is the modem dialer to connect to the ISP so I'm not sure which one is meant to have an IP address (assuming dialer). I have attached my updated config for your reference. Thanks again for your help so far. Edit: Config attached to latest reply. ... View more

Thank you very much for your reply, unfortunately it didn't seem to change anything which leads me to think that maybe my ATM/Dialer configuration is incorrect. I appreciate that you haven't used this particular router but wondering if you could have a quick nose around the rest of the config to see if anything is obviously wrong there. As I've made a few changes since my original post, here is my updated config attached. Do you know if there is a way to see the status of the dialer/ATM interfaces to see whether it's picked up and IP from the ISP? Thanks for the help so far! Edit: Latest config is in latest reply. ...
