Hi @marccampbell,


Thanks for reaching out to us. We'd like to help. Would it be possible for you to post a screenshot of your port-foward settings and we'll have this checked.

My experience with port forwarding on the HG659 is that port forwarding works well when forwarding to a computer on the LAN. However, if the computer is connected to the modem via WIFI, then the port forwarding stops working after a while - just as you have experienced.

From my observations, I think that this happens because WIFI connections are temporary and each time a WIFI link is created the HG659 creates an entry for that connection in its table of connections. Unfortunately, that table has a fixed size and eventually it gets filled up and when that happens, the modem throws away an old entry. If that entry corresponds to the one created for the port forwarding you are just out of luck!

I also noted that the modem does not clean up this table when it is power-cycled, which prevents us from maintaining the port forwarding configuration by rebooting the modem before the table fills up...

If anyone know how to get port forwarding to work over WIFI please let me know as I am interested!!

Exact same issue. Same with dmz. Works until the pc/xbox is turned off or disconnected

Is your pc/xbox connected via WIFI or wired LAN?

Xbox and pc is connected by wifi, both have a static ip. Thanks

Based on my experience, using a static ip address with WIFI does not really help with this problem.  As dynamic IP address allocation does not guarantee the same IP address will be assigned to the same device each time, using a static IP address for the device to port forward to is a necessary condition but it is not sufficient with the HG659. If you can, try to connect (at least temporarily for the test) your PC and/or xbox with a cable to the LAN ports on the modem and give it another try. From my observations this works reliably.


Good luck!
