ORBI - Port 443 Closed even with Port Forwarding?
I have an RBR50 connected to an AT&T modem/router with IP passthrough. Synology web server is connected to the Orbi. Port Forwarding is enabled for 80 and 443 between Orbi and Synology. Howev...
Solution discovered:
I have AT&T as a service provider for Fiber; formerly I also had their U-Verse service with wireless receivers/DVR's.
Come to find out AT&T does block Port 443 for any inbound traffic. They specifically use this port for their wireless receivers/DVR's. Despite cancelling U-Verse last year, the IP/MacID of these services were still listed/cached in the AT&T modem/router which resulted in a permanent closure on Port 443.
SOLUTION FOR USERS WITH A SIMILAR ISSUE (assuming you do not have wireless receivers and just ATT fiber):
1. Login to ATT's modem router admin portal at 192.168.1.254
2. Click on Device>Device List>Clear and Rescan for Devices.
3. Perform a factory reset of the AT&T BGW210 modem/router, add port forwarding rules for allowed ports, then re-configure it for IP Passthrough to the Orbi again.
4. Apply or disable any additional settings needed for a secure network hosted by ATT or the Orbi.
This is probably a good solution for anyone with the following or similar equipment:
- At&t Arris bgw210-700
- Orbi
- Home NAS

"AT&T" (your ISP) and "the AT&T BGW210 modem/router" are two
different entities.

I'd expect the tests suggested in "3" to have revealed such a problem
pretty easily. If "from a system on your LAN, try using the router's
WAN/Internet IP address" works, but actual outside-world access fails,
then something on the ISP side of the RBR50 would seem to be implicated.
