      Hi,

      I have an issue where I'm connecting to a pfSense running CE 2.7 using OpenVPN and when running an Iperf test it hangs for a bit and it says the transfer rate is 0.00 bits/sec for up to 224 seconds then it starts transferring

      Here is my OpenVPN config

      dev tun
      persist-tun
      persist-key
      data-ciphers AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305:AES-256-CBC
      data-ciphers-fallback AES-256-CBC
      auth SHA256
      tls-client
      client
      resolv-retry infinite
      remote pfsense wan ip 1194 udp4
      setenv opt block-outside-dns
      nobind
      auth-user-pass
      ca pfSense-UDP4-1194-ca.crt
      tls-auth pfSense-UDP4-1194-tls.key 1
      remote-cert-tls server
      explicit-exit-notify

      I've fixed this before by playing with the mssfix option but this doesn't seem to work recently. I've tested across a site to site VPN and transfer rates are good so it seems like an OpenVPN issue. Thanks for any help!
