OpenVPN VoIP interrupts after pfSense 2.5.1 release installed
Maybe one of you can help me. I am a little desperate here.
Two weeks ago we installed the major release upgrade to version 2.5.1. Before that we were using 2.4.4. Since then we do not have a stable OpenVPN connection.
There are irregular interruptions during the VoIP connection that last up to 3 seconds. At the same time, during an endless ping of the VPN client to the VoIP server, a high latency (3000ms) up to a timeout can be measured.
A downgrade to the previously used version solves the problem.
A test with a changed hardware appliance, which has much more performance, leads to the same interruptions but with lower latency. (around 1500ms)
No settings were changed after the release upgrade. The OpenVPN server was updated with the pfSense release upgrade from 2.4.6 to 2.5.1. There are certainly some major changes there but I couldn't find the bug with it so far.
Our installation runs on a PCengines apu3b4 (3 i211AT LAN / AMD GX-412TC CPU / 4 GB DRAM).
this is our config
I hope it is alright to put the same request translated in the german part of the forum.
Thanks for the support.
