How to forward a port on Arris DG2470A

Port forwarding should be fairly straightforward, but what Arris doesn't tell you is that you need to have the firewall on in order for port forwarding settings to have an effect.

I don't know why the "firewall off" option would mean "block everything", but as best I can tell, that was the case on my Arris DG2470A (from RCN, could be some custom firmware that RCN uses?)

So step by step:

  1. Go to your gateway address (mine was 192.168.0.1)
  2. Login. Default user/pass is admin/password
  3. Go to the "Firewall" tab.
  4. Ensure that "Enable Firewall" is checked. (Be sure to hit "Apply" if you have to check it)
  5. Click on "Virtual Servers / Port Forwarding" on the left.
  6. Add an entry for your desired port and internal ip etc. (If you're just forwarding one external port to the same internal port, then you'll end up typing that same port # four times, twice in each range)
  7. Save.

Hopefully this saves you some time.
