Overview of Telegram Proxy Servers

Telegram can use two types of proxy servers: SOCKS5 and MTProto. The proxy server may be either public or private. There are therefore four possibilities.

• Use a public SOCKS5 proxy server
• Use a public MTProto proxy server
• Create a private SOCKS5 proxy server
• Create a private MTProto server, as described at https://github.com/TelegramMessenger/MTProxy

The user specifies the proxy server in the Telegram client by going to Settings > Data and Storage > Proxy.

For a SOCKS5 proxy server, the information required is the server hostname or IP address, the server port number, and optionally a username and password.

For an MTProto proxy server, the information required is the server hostname or IP address, the server port number, and the server “secret.”
