Using OpenVPN Protocols
If you're using a VPN to watch movies on Netflix or Showtime or to visit one of China's or Iran's numerous restricted websites, you'll need to try some more complicated maneuvers. Changing the port you utilize over your VPN is simple with OpenVPN protocols. Both Port 80 and Port 443 are frequently successful in bypassing VPN barriers. OpenVPN was created as an open project in 2001, which implies that anybody may use and criticize its source. This has given rise to a community of programmers who test, enhance, and upgrade the protocol on a regular basis.
This is the foundation of all open-source software. Because it is not proprietary code (i.e. controlled by a single corporation), security professionals from all over the world may use it to ensure its security. Similar to how Wikipedia benefits from the capacity of the community to check facts and fix errors, OpenVPN benefits from this community of security experts.
