I currently have a Cisco 2611 (12.3) that is connected to a Zyxel ADSL modem. The router provides NAT/VPN and firewalling for the internal network.
I have purchased a WIC-1ADSL to replace the Zyxel, but before I install, I'm trying to understand the configuration options I have.
My ISP provided me with the VPI/VCI info (0/35) and the fact that they are running PPPoA in bridged mode.
This makes sense to me with the external Zyxel device connected to the circuit and then to my router...but how does this work when the "bridge" is internal to the Cisco router itself? Where are my public IP addresses and what interface will they be assigned to for routing to the internal, private network?
Can someone explain this to me or point me to documents that will help me understand this?
