How to setup a WAN interface

If for some reason the MAC address is not registered with the UIC DHCP server for the desired hostname, you must contact UIC CS Support to register the address you wish to use. Otherwise, collect the MAC address registered for that hostname from the config book in the server room. Adding the interface and activating it is then as simple putting the MAC address into the example config below, picking a network device name, and activating it with the netctl command.

Afterwards, proceed to the firewall page to configure routing and the firewall.

If you Restarted the Server...

  1. Don't do it again.
  2. Reacquire IP addresses from DHCP with: sudo dhcpcd -t 0 -4 wmac1.
  3. DO NOT do it again.
