Good Morning List I have now come across a problem that exceeds my ability to solve... that's why I'm asking for help here.
Current Situation (running since 2012): A Server with Debian-Bookworm with OpenVPN 2.6.6 x86_64-pc-linux-gnu and some clients with Android or Debian Bookworm. 2 OpenVPN-Instances are running on the server, 1 UDP at Custom-Port and 1 TCP at 443. The TCP-Instance is a rarely used Backup-Instance, in case UDP-Traffic on private/public WiFI is blocked at Ports >1024 - this happened in some places in Sweden where open WiFi was offered. All Clients are working perfect with my OpenVPN at Home on any open Third-Party-WiFi Accesspoints. They also working perfekt, if one Android-Phone open a Mobile-Hotspot with his own Mobile-Connection. The current Problem: Without any open WiFi-Network, however, I also use a small LTE-Router. With a TCP-Connection to my Home-Server it is the same as before… it running perfect. But UDP did not work properly… it seems, it runs in a super-mega- slowmotion. They crazy thing is, an error-free connection is established first. When I check on the go (see below), all is good: -My public Home-IP is used, not the Mobile-IP. -Google is reachable -GMX is found with pings -My Server is also found The Ping-Time to GMX is almost the same as before without OpenVPN or very close to it. The connection is okay, no errors are reported in Logs, all seems to be okay - but nothing works: -SSHFS to Server try to connect until it breaks -Mounts try to connect until they breaks -View to Cams try to connect until it breaks -Browser try to connect and breaks all Websites It seems to me, that all breaks after a timeout done and i don’t know, where the Problem is. I would be very happy to receive helpful advice.
