Hello, I just recently received the HUMAX BGW320-500 from AT&T for our 1gbps fiber internet upgrade from a much older Pace PLC router but now after upgrading, I am no longer able to open port 443. I have pointed 443 to my server and it shows as opened in the router in the NAT/Gaming section. It’s also opened on my server. I opened it with UFW. Before I had no issues though I had a DMZ setup before (I know I know not super secure but it was only temporary) but now I cannot get anything open.
The BGW-320 is less than ideal for certain power users and hosting scenarios. There are a few methods to bypass it depending on your connection type (GPON or XGSPON).
