||OpenVPN (Virtual Private Networking) - it is newer, secure form of VPN that uses open-source technologies and is preferable to PPTP and L2TP. OpenVPN uses the OpenSSL encryption library and SSL v3/TLS v1 protocols. It listens on port 1194/UDP by default. However, it can be configured to run on any port, like 443/TCP that makes it undistinguishable from HTTPS traffic, for example.
Ooma VoIP service sets a VPN to the Ooma servers on port 1194 UDP for call setup/control. It also uses ports 49000-50000 for actual VoIP data. Other ports used: UDP 3480, UDP 514, TCP 443
QNAP NAS uses port 1194 UDP for OpenVPN connections. QNAP also uses the following ports: 873,8081,8899,1723,13131,20001.
||OpenVPN, registered 2004-11
Related ports: 443 514 873 1723 3480 5060 8081 13131 20001

SANS Internet Storm Center: port 1194
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify
a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly
used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol
on the Internet and any TCP/IP network. TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol)
and facilitates the transmission of datagrams from one computer to applications on another computer,
but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
