TCP Proxy

Proxy TCP traffic to a service by creating a TCP proxy.

How it works

Enabling TCP Proxy on a service requires specification of a port to which the traffic should be proxied. Railway then generates a domain and proxy port, and all traffic sent to domain:port will be proxied to the service.

Load Balancing

Currently we use a random load balancing strategy for TCP traffic.

Use Cases

TCP Proxy is useful for services that don't support HTTP, such as databases.

Support

For more information on how to set it up, refer to the TCP Proxy section of the Public Networking guide.
