Not every service speaks HTTP. Techulus Cloud supports exposing raw TCP and UDP ports through proxy nodes for services like databases, game servers, or custom protocols.

​
Configuration

When adding a port to a service, set the protocol to tcp or udp:
FieldDescription
PortThe container port your service listens on
Protocoltcp or udp
External portThe port exposed on the proxy node
PublicWhether this port is accessible from the internet
Traffic is routed from the proxy node’s external port through the WireGuard mesh to the container.

​
TLS Passthrough

For TCP services that handle their own TLS (e.g., a database with native SSL), enable TLS passthrough. This forwards the encrypted connection directly to the container without Traefik terminating TLS.

​
Firewall

The agent setup script configures firewall rules to allow traffic on the TCP/UDP proxy port ranges. If you set up servers manually, ensure the relevant ports are open.
