Hi There,
Has anyone been able to get a Vigor 120 to work with standard BT Internet PPPoA ADSL to a CISCO ASA 5505 device. I have the CISCO ASA already fully configured and can see the extenal ip address but there is no traffic in or out.

Thanks

Have not use it but maybe some troubleshot links will helps you
connect first the 120 to your pc and give manually the correct settings from your isp

also check firewall rules with your cisco maybe try turn it off
Also check DNS / DHCP at both ... personal i think the problem may be there
