How to open a port on the O2 TG585

O2 O2-TG585 v7 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static ip address on either your computer or device that you want to forward a port to.
  2. Login to your O2 TG585 router.
  3. Navigate to the port forwarding section.
    • Click the Toolbox button.
    • Click on Game & Application Sharing.
    • Click the Create a new game or application link.
    • Enter a name in the Name box.
    • Click the Manual Entry of Port Maps radio button.
    • Click the Next button.
  4. Create a port forward entry.
