Feb 01, 2019 · OpenVPN is much more secure since it can use better encryption for authentication, such as SHA-256, SHA-384, or SHA-512. Furthermore, PPTP is pretty easy to block with a firewall. OpenVPN can’t really be blocked by the network admin since it uses the HTTPS port. Oh, and let’s not forget that the NSA can apparently crack PPTP traffic.

Apr 16, 2019 · OpenVPN does not obfuscate connections by default, so even if you are using TLS on Port 443, your internet service provider (ISP) can assess your traffic using Deep Packet Inspection (DPI) and To counter @ThomasWard's point; You absolutely can run openvpn on port 80, without any trouble.

Feel free to mix and match! Apr 12, 2018 · 80: HTTP 433: HTTPS 1194: OpenVPN. Port Forwarding to Port 443. The most effective way to bypass firewall restrictions is to forward VPN traffic to port 443, given that by default, this port is used for encrypted TLS/SSL traffic. VPN Port 80 is often used in encrypted communication. It is also known as the HTTP port. This means that it is used for accessing websites with http://. Therefore, it is not possible to block Port 80. Often on locked-down networks, only ports like 80 and 443 will be allowed out for security reasons, and running OpenVPN instances on these allowed ports can help to get out in situations where access may otherwise be restricted. Then a port number is needed. The official OpenVPN port number is 1194, but any port number between 1 and 65535 will work. If you don't provide the 'port' option, 1194 will be used.

If your server has only an IP address, then use that in your browser. For example if your OpenVPN Access Server has the IP address 123.45.67.89 then by default the Access Server should listen on that address. By default the OpenVPN Access Server installs the web interfaces on port TCP 943, and also makes them available at port TCP 443.

The port you choose doesn't affect the security of the VPN. Using different ports only helps to avoid/bypass firewall rules. Of course if network administrators inspect your traffic they'll detect that you're using a different protocol than the usual for that specific port (f.e. HTTP for port 80).
