BGW320-500 Port Forwarding Not Working

We understand, and we're here to assist with your port forwarding, @ArchV1!

To forward ports on the BGW320-500 modem, you can try the following steps:

• Login to the BGW320-505 modem by going to the IP address printed on the modem (192.168.1.254)
• Go to Firewall > IP Passthrough > Set Allocation Mode to Passthrough
• Passthrough Mode: DHCPS-fixed, then select the MAC address of your router from the list
• Enter the Device Access Code found on the side of your gateway
• Select NAT/Gaming
• If you receive a warning message, visit the AT&T Port Forwarding tool to enable port forwarding on your account
• Alternatively, you could set up IP Passthrough to your own router, then set up Port Forwarding in that router4

Let us know if this helps.

For further assistance feel free to get back to us!

I don't have a second router.  Port forward should work on the AT&T device alone.

How do I do this step?  If AT&T has port forwarding blocked at the account level, this is certainly the problem:

If you receive a warning message, visit the AT&T Port Forwarding tool to enable port forwarding on your account

Thanks

@ArchV1 , are you 100% sure that the port is actually open for access off the server PC?  A quick test would be to try to access it from another PC on your network using the private IP address.  If that works, then, you should continue to look at Port Forwarding issues.  If that doesn't work, then you need to find out why:

• Is the software not running?
• Is the software not opening the correct port?
• Is the OS (or other third-party software) firewall blocking the access.

Check to make sure the software is running (start it, check the service, etc.)

You can search the output of "netstat -a" to see if your port shows up as a port being listened to

Check the log of your firewall and/or the configuration to ensure it will pass the traffic.
