What is port 1194 used for?

Port 1194 is the standard TCP/UDP port used for OpenVPN. It is commonly used by OpenVPN Community Edition, OpenVPN Access Server, PFSense. Established SSL/TLS-based virtual private network protocol implementing secure point-to-point and site-to-site tunnels.

How do I check if port 1194 is open?

Enter your public IP or hostname into the scanner tool and click Check. A sub-second raw TCP socket handshake will be initiated from our edge server to port 1194 on your target. If the 3-way handshake finishes with SYN-ACK, the port is OPEN. If an RST packet is returned, the host is reachable but the port is CLOSED. If packets time out without response, the port is FILTERED by an ISP or firewall.

Is port 1194 safe to expose to the public internet?

Port 1194 is generally safe to expose when running standard, patched services with strong authentication. However, always ensure your software is updated and access control policies are strictly enforced.

Why does port 1194 show as closed or filtered?

If port 1194 reports CLOSED or FILTERED, confirm that: 1) Your service is actively running and bound to 0.0.0.0 (not just localhost/127.0.0.1); 2) Your router has a port forwarding rule directing external port 1194 to your machine's local IP; 3) Your operating system firewall (Windows Defender Firewall, ufw, or iptables) allows incoming connections on port 1194.

Port Forwarding & Troubleshooting Checklist

If port 1194 returns CLOSED or FILTERED, work through this verified diagnostic checklist:

1 Verify whether your OpenVPN daemon is configured for UDP 1194 (default) or TCP 1194 in server.conf.
2 Check router port forwarding matches the exact transport protocol (UDP vs TCP).
3 Inspect server logs via 'journalctl -u openvpn' to ensure daemon is active.
