I understand that you can have your own device establish the pppoe but what I'm interested in is having the sagemcom 2864 take care of that and pass along only the "public ip". From what I understand that is a capability on some dsl modems.
What's happening in my case is that if I want my router to accept a "dynamic" or "static connection" verses "pppoe" , I'm getting a private LAN IP i.e. 192.168.x.x instead of the public IP. I've tried disabling dhcp in the settings ultimately it just disables any connectivity to the ports.
Examples of passing "public IP" : »hardforum.com/showthread.php?t=1579486
I hope what I explained here makes more sense ?
