887va-K9 - Configuring a Fast Ethernet switch port as a WAN interface with PPPoE

[cisco123456]

Hi all, my first post here, this is actually a follow up to thread557-1730859

The OP was having difficulty using an Ethernet Port to connect to the internet as opposed to the ADSL/VDSL port intended for that purpose. Although he did get it working, he didn't post his final working config. I was having the same difficulty, and the Cisco Configuration Professional software doesn't give you the option to configure the router in that way via the GUI

Using some of the config from the aforementioned thread, cross referenced with some other research, I was able to come up with a working configuration. In my example, Fast Ethernet 0 is the LAN port, and Fast Ethernet 3 is the WAN port. DHCP addresses will be given out on the LAN, in the 10.10.10.x range. The WAN port (or more specifically the dialer linked with the WAN port) is configured to obtain it's IP from the ISP. PAP is used for the PPPoE authentication, and NAT is in use between the LAN and the internet. The model router I have is the 887VA-K9

Substitute anything you see in angle brackets with values specific to your connection

Enjoy!
