Can I use Tor through UDP Protocol?

Tor only supports TCP. Non-TCP traffic to the Internet, such as UDP datagrams and ICMP packets, is dropped.

Why does Tor not support UDP?

Tor Design[edit]

The current Tor design does not support the transport of UDP-based protocols through exit nodes in the network. This is unlikely to be supported in the near future due to incompatibility with cryptographic protocols in use and those planned.

What protocol does Tor use?

TCP: Typically, Tor uses TLS over TCP as its transport protocol. The well known TLS port for Tor traffic is 443. Tor commonly uses ports 9001 and 9030 for network traffic and directory information.

What ports need to be open for Tor?

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) ports commonly affiliated with Tor include 9001, 9030, 9040, 9050, 9051, and 9150.

Does Tor use TCP IP?

Tor also uses the same servers, the same TCP/IP protocol, and the same encryption algorithms that the normal internet uses. Tor provides private connections over the public internet by using misdirection.
