Recent AT&T firmware upgrades breaking application pinholes?
For a long time I had a pinhole set up on my 5268 router that was working perfectly. Then about 3-4 months ago it stopped working. Not a showstopper - I had a workaround. At that time, I had a strong suspicion that it was due to a recent firmware update that had been installed. Recently I've grown tired of using the workaround (it's a hassle to use and has some negative side effects) so I called support, we went thru a few basic troubleshooting steps, but in the end they sent me a new router. The new router had firmware version 220.127.116.112678-att. I set up the pinhole and I was amazed that it actually worked (I expected the router to come with latest firmware that I thought was broken). But then later that night (or early next morning) at 2am I watched as the router shut down then restarted - obviously a firmware update and my heart sank. Would my pinhole still work? NOPE. I confirmed in the Upgrade Logs that version 18.104.22.1682887 had just been installed. Now again, like before when it first started happening, I get firewall logs that say "IN=br1 MAC=14:ed:bb:XX:XX:XX SRC=X.X.133.4 DST=99.X.X.X TTL=107 PROTO=UDP DPT=51502 Drop Unknown Incoming Packet" even though my firewall status screen shows the pinhole is still configured:
|Device||Allowed Applications||Application Type||Protocol||Port Number(s)||Public IP|
(I've randomized/anonymized the actual values and hidden my IP and actual port number for privacy, but the essential representation is still accurate. And to be clear, the Linksys is another router that I have inside the AT&T router for additional ports and additional security. The Linksys is NOT the problem - everything worked fine with this same setup, when it worked.)
I'm about at the end of my rope for tolerating this issue. AT&T says they cannot revert to a previous firmware. I could do that by doing a factory reset, but there's nothing that would stop the firmware from upgrading again every night. They've been unable to resolve the issue with the pinhole.
Am I the only one experiencing this??? I don't want to switch back to Spectrum, but only because it's a hassle to go thru. But if AT&T can't fix this then I will have to do exactly that. I want to give them every last possible chance, so I'm posting here because it's my last hope. For the record, everyone I've talked to at AT&T tech support has been very friendly and wanted to help, so I'm not bitter... but they haven't been able to solve the problem, because I don't think there is a solution immediately available - I'm pretty convinced that the firmware is just broken. I'm just frustrated and hoping someone here has gone thru this and found a solution.
