2 edits | Question About Port Forwarding With 2210-02 Modem (ATT SW)
Wasn't sure where to stick this thread, but I feel that it's more of a hardware than ISP issue. Now, with this firmware that's installed on this modem, I can't seem to find anywhere to forward ports and it's causing me some major confusion. In addition to this, I have my modem connected to a Netgear Prosafe Desktop switch.
The picture I've attached shows all the things that I can see when I go to this modem's UI. In addition, the only option it seems I can change on the modem is the "PPP Location" option which lets me select between "PPP on the modem" , "PPP on the computer", or "Bridged Mode."
When I selected "bridged mode", I was able to forward ports through my software firewall. However, when I did it, I had to enter what seemed to be my external IP address rather than my chosen static IP of 192.168.x.x nature and I felt that that would only serve to be a temporary fix due to foreseeable modem unplugging. In addition, I don't know why, but I also didn't feel like it was quite safe to enter my external IP rather than a static one.
On the other hand, I can't get it to configure at all when I select the other modem operation mode. The "PPP on the modem" option always gives me messages of failed port checks and even turning off the firewall completely doesn't work.
Next up, I try the other mode. When I pick "PPP on the computer", this time I AM able to forward ports if I disable the the firewall, but I can't seem to forward them when I try to configure my firewall for it.
Does someone have any ideas for me? Also, since I don't know if this modem even has a hardware firewall, what would the safest operation mode be for me? |

| Fromthetopg  , I have moved your post to the AT&T Southwest forum to see if someone familiar with your modem can help you out.

The modem passes all ports. There is no firewall.
What does your "Connection Information" panel say?
Many of us run with "PPPoE on the modem" so that it can do all the dirty work with the PPPoE stuff. Then the router's firewall and port forwarding stuff works properly |

Oh yes, had to give my update on this issue. I was able to finally portforward correctly, but I wasn't able to do it by setting a customized static IP.
The way I was able to do it by first setting the modem back to it's original setting of 'PPPoE on the modem'.
I next typed 'cmd' into run on the start menu and then typed in 'ipconfig' into the window that came up.
After that, I searched for the modem's IP address which was displayed as 192.168.1.xx.
Then I simply created a network zone and some global rules in my firewall (Comodo) to allow certain programs to access certain ports.
I still wish I could've set a custom static IP of the 192.168.1.xx range but as it stood, that would do. |
