Replacing the CenturyLink provided ethernet router with OpenBSD
Unfortunately CenturyLink provisions their fiber to the home with a PPPoE authentication over vlan 201, this makes replacing the router more difficult than it should be. I also had to call CenturyLink support to get the password for the PPPoE connection.
cnmac0 is the egress interface on my EdgeRouter Lite.
