Point to Point VPN Becomes VERY Slow After Hours or Days - Service Restart Fixes
-
We have four locations using pfSense (OpenVPN) to connect to our main location (Star Topology). We have a strange issue where the connection goes to crap after anywhere from a few hours to a few days. A simple restart of the client service fixes the problem every time. There are no errors shown in the OpenVPN logs.
Each location is running a VM of pfSense 2.1.5.
Each location is connected via Comcast Business Internet at 100/15
When things are running like crap over the VPN, the internet connection is still full speed according to Ookla / Xfinity Speed test.Over the VPN I see speeds drop from 100 Mb/s to 1-2 Mb/s
Any idea what could be causing this? Obviously its an issue with the OpenVPN client since a restart fixes things.

Don't see any such thing ever. Are you sure it's not lovely comcast doing shenanigans with a long-established session?

I suspect this is the most likely scenario. It hasn't happened in a while now at least.
