Not every service speaks HTTP. Techulus Cloud supports exposing raw TCP and UDP ports through proxy nodes for services like game servers or custom protocols.
Database exposure warning: Do not expose database ports publicly through the TCP/UDP proxy. Public database access increases security risk, and Techulus Cloud does not provide HA storage or automatic failover for production databases.

​
Configuration

When adding a port to a service, set the protocol to tcp or udp: 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, 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.
