Hi,
I have a C2600 that I want to use as a gateway to my ISP. The ISP is providing their service using PPPoE. ISP have several PPPoE services under different Service-names, but I was not able to get the Cisco box to request the right service. In any way it is selecting one of the services I am not eligible for and the authentication fails.
Here is how it looks like on the packet level. pppoed = PPP-over-Ethernet Discovery
Cisco box

I found some post on the net that I should use username@service-name in the line
ppp pap sent-username user@service-name password pass...
but this is not working for me at all. So any idea how can I make cisco box to request the db1 service?
Thanks in advance!
