Having some trouble port forwarding. I followed the guide for my specific router, BGW210 (https://www.att.com/support/article/u-verse-high-speed-internet/KM1215101). I live in an apartment complex that already had AT&T Fiber InstantOn.
When I go to check if the port is open (https://www.yougetsignal.com/tools/open-ports/), it still says it is closed. I've also set new rules in my Windows Defender Firewall settings (TCP and UDP). I've restarted my device. Tried deleting and writing the rules again. Nothing seems to open the port. Not a network guy so I don't know what I'm doing wrong or how to best proceed.
