Port Forward OpenVPN through TCP port 443Д«y far the simplest method, one that can be easily performed from your (the client) end, requires no server-side implementation, and will work in most cases, is to forward your OpenVPN traffic through TCP port 443. If hiding your VPN signal is important to you and Port 443 forwarding (see below) is insufficient, then you should contact your VPN providerВ to discuss whether they would be willing to implement one of the solutions outlined below (or alternatively find a provider, such as AirVPN, who already offers this type of support).

There are a number of solutions to this problem, but most of them require a degree of technical expertise and server-side configuration, which is why this article is simply an introduction to the options available. The problem is that while it is impossible to вЂseeвЂ™ the data in an encrypted VPN tunnel, increasingly sophisticated firewalls are able to use Deep Packet Inspection (DPI) techniques to determine that encryption is being used (to detect for example the SSL encryption used by OpenVPN). China, with its Great Firewall, has been particularly active in this regard, and there have been many reports from people using a VPNs in China having their connections blocked.

As internet censorship tightens across the world, governments are becoming more and more concerned about preventing the use of VPN to circumvent their restrictions.
