Telenet and Unifi

Some months back a friend of mine wanted to switch over to the Unifi platform (which I’ve been using now for about a year), and get it to play nice with his Telenet ISP setup aswell.

This means:

• Getting WAN IP addresses to the Telenet Digicorders
• Getting a WAN IP to his Unifi Secure Gateway
• Making the USG the DHCP server (and everything else) for the rest of the network
• Making sure all the traffic from the LAN remains isolated from the WAN

With Unifi, this is fairly easily to solve. The following assumes you’ll be using a Unifi controller version 5.12 (or higher), as the menu structure changed drastically between 5.11 and 5.12.

• Create a new network:
  Settings → Networks → Local Networks
  Create a new Advanced Network of the type VLAN. Set the VLAN ID to something that you haven’t used before. We’ll call this “Telenet WAN”
• Create a new switch profile:
  Settings → Configuration Profiles → Switch Profiles There should be a new switch profile visible with the same name as the Network you created earlier. If not, create it.
• Configure switch ports: Devices → Select switch → Ports
  Configure the ports as follows: Port of the Telenet Modem, USG, digicorder: Select the “Telenet WAN” profile Port of the USG LAN: LAN profile All other ports: LAN profile

This will make sure that all traffic behind the “Telenet WAN” ports will get routed to the Telenet modem, and the rest via the USG ;)
