I am having an issue with AT&T Fiber and a Double NAT issue; I have already set the modem in bridge mode and done the required port forwarding to two servers, but I keep loosing the connection.
Internal IP is: 10.100.1.136
External IP: 71.XXX.XX.XXX
The servers worked great when I was using a different service provider. What do I need to tell AT&T?
I have T-Mobile Home Internet now, and I’m experiencing a similar issue. Plex keeps showing an error message, indicating that double-NAT is still a problem, but I’ve done everything to address that as far as I can tell.
Good luck, and hopefully AT&T can give you some actionable intel.
Oddly enough, my server has been available from remote access, having done nothing to change the configuration. The remote access setting still says that my server is not available, but I can stream music from both Android and Windows at full quality. I’m afraid to change anything, and risk making it inaccessible again.
When I do lose access again, I’ll try your solution and see if I can get it configured like that. Unfortunate that AT&T didn’t help you out, but at least you did find a solution that works. Thanks for updating the thread with the info!
