OpenVPN is an open-source VPN protocol known for its robust security features and flexibility. It can operate on various ports and supports multiple protocols, including UDP (User Datagram Protocol) and TCP (Transmission Control Protocol).

Some advanced firewalls use Deep Packet Inspection (DPI) to look inside the data packets. If the firewall discovers that the data on Port 53 is encrypted VPN traffic rather than actual DNS queries, it may throttle or drop the connection.

To understand the significance of this specific configuration, one must first understand the mechanics of internet censorship. Firewalls act as gatekeepers, inspecting data packets as they enter or leave a network. A standard unencrypted connection is easily identified and blocked. Even standard VPN connections, which typically operate on known ports like 1194 (OpenVPN default) or 443 (HTTPS), can be identified by their digital "handshakes" and blocked by sophisticated Deep Packet Inspection (DPI) systems. When an administrator sees traffic on port 1194, they can safely assume it is VPN traffic and shut it down. This is where the genius of the UDP 53 configuration comes into play.
