Port 1080: SOCKS

Port 1080 is the default port for a SOCKS proxy, which relays arbitrary TCP, and in SOCKS5 also UDP, traffic on behalf of a client without understanding the application protocol inside it. SSH's built-in dynamic port forwarding (ssh -D) creates a SOCKS proxy on a port like this one.

Security note. Port 1080 is not encrypted by default. Restrict it to trusted networks, or use an encrypted alternative where one exists, to avoid exposing credentials and data in transit.

Frequently asked questions

What is port 1080 used for?

Port 1080 is the default port for a SOCKS proxy, which relays arbitrary TCP, and in SOCKS5 also UDP, traffic on behalf of a client without understanding the application protocol inside it. SSH's built-in dynamic port forwarding (ssh -D) creates a SOCKS proxy on a port like this one.

Is port 1080 TCP or UDP?

Port 1080 (SOCKS) uses TCP.

Is port 1080 secure?

Port 1080 is not encrypted by default. Where possible, use an encrypted alternative or tunnel it over TLS or a VPN.

Should I open port 1080 on my firewall?

Only if you specifically need SOCKS. Expose it to the smallest set of trusted sources, and never open database or Windows-service ports to the whole internet.
