AT&T DSL 2701HG-B Modem, port forwarding to RealVNC

Question

Our old cable modem could easily be set up to forward an "incoming port request" to the RealVNC software. Allowing us to log into our home computer from any location.

We don't see any such configuration possiblity with our new AT&T DSL 2Wire 2701HG-B modem.

(And it appears to have 2 entirely different 'set up screens'. Why?)

Where is the screen that allows "forward incoming request for a certain port", to a certain computer, and direct it towards RealVNC"?

Answer 1

Head over to your Router setup page, Click on Firewall section:

Click the Firewall Settings button.

Use the Select a computer box to choose a computer to forward ports to. Click the Add a new user-defined application link. RealVNC requires you to forward the 5900 ports. Enter port range as 5900 in From & To Boxes, for TCP & UDP protocols in Edit Application menu and then click Add Definition.

Click the Back button. Select the applications you just created in the Applications list, then click the Add button to move them to the Hosted Applications box. When you are finished, click the Done button at the bottom of your screen.

Save the page, port forwarding is active now
