@Pippin Thank you for the reply. I went into VPN -> OpenVPN -> Clients and edited my client's configuration. Under Advanced Configuration I put into the custom options "ns-cert-type server; persist-tun; persist-key; mssfix 1400" and then saved. I then reloaded the VPN by going to Status -> OpenVPN. I did the usual ping/nmap verification checks to confirm connectivity. However this does not seem to have done anything. Below is a picture of the wireshark output (with the TCP stream from the browser being currently selected) and below that is the capture file. mssfix1400_full_cap.pcapng
