Slow VPN speed on OpenVPN through PFSense
-
Hello.
During last few days we have implemented OpenVPN through pfsense Community Edition (version 2.7.2) on Proxmox 8.2. Our authentication is making request on our local LDAP and it is working perfect. Also VPN connection is making requests and cllients are able to connect.
Problem which we are seeing now is very low speeds when VPN is connected, example:
Our user having at home connection 1GB/100Mb. He run speedtest before VPN and gets next results:
After, when he connect to VPN (OpenVPN) he gets 5% of initial speed - network mode is UDP, on TCP is even slower:
During the installation we have go through documents with settings and we made next settings on Proxmox:
Also on pfsense we have disable next things:
If we run speedtest directly on pfsense server we are getting next results:
Please help us to make this works as it should!
Thank you very much!!
