I’m currently running a site to site open VPN from my HQ to five outstations just so the remote users can access an product distribution software. However, The ISP I have can only offer 2mb up and down. I noticed my Ping test breaks from time to time hence making the software access very slow. How best can I fine tune the site to site pfsense OpenVPN to give me a better perfomance
There is not a lot you can do to help a 2mb connection. I would make sure you are configured as split tunnel so only the traffic for the local resources on the VPN is going over the tunnel.
