Main Thought
Understanding the ports used by VPNs and the protocols they rely on is crucial for anyone using or considering a VPN service.
Key Points
1. The Most Common VPN Ports
By default, VPNs use specific ports depending on the protocol being used. For example, OpenVPN commonly uses UDP port 1194 and TCP port 443. IPsec/IKEv2 uses port 500, and PPTP uses port 1723.
2. The Four Main Types of VPN
There are four main types of VPNs: Personal VPN, Mobile VPN, Remote Access VPN, and Site-to-Site VPN. Each type serves a different purpose and caters to specific networking needs.
3. OpenVPN and Port 443
OpenVPN, a popular VPN protocol known for its security, can use both UDP or TCP protocols. TCP port 443 is commonly used to ensure compatibility with firewalls and bypass restrictions.
4. PPTP and Port 1723
Point-to-Point Tunneling Protocol (PPTP) uses TCP port 1723 and IP protocol 47 Generic Routing Encapsulation (GRE). PPTP is often used to establish low-cost, private connections to corporate networks.
5. UDP vs. TCP
VPN connections can use either UDP or TCP protocols. TCP is more reliable but may sacrifice performance, while UDP is often preferred for activities that require speed, such as gaming or streaming.
6. SSL VPN and Port 443
Mobile VPN with SSL commonly uses TCP port 443 as the default protocol and port. SSL VPNs provide secure remote access to networks using the SSL/TLS protocol.
7. VPN Port 500 and IPSec VPN
IPSec VPN uses port 500 for Internet Key Exchange (IKE) and port 4500 for IPSec NAT-Traversal (NAT-T). It offers a layer 3 protocol for secure communication between networks.

What is port 1723 used for
Point-to-Point Tunneling Protocol (PPTP) uses TCP port 1723 and IP protocol 47 Generic Routing Encapsulation (GRE). PPTP provides a low-cost, private connection to a corporate network through the Internet. PPTP works well for people who work from home or travel and need to access their corporate networks.
Is A VPN UDP or TCP
TCP is more reliable, but there are many uses where UDP is preferred and this is usually the default protocol on most VPN services. UDP is a great option if you are gaming, streaming or using VoIP services.
What port is 3389 used for
Remote Desktop Protocol (RDP)
Overview. Remote Desktop Protocol (RDP) is a Microsoft proprietary protocol that enables remote connections to other computers, typically over TCP port 3389. It provides network access for a remote user over an encrypted channel.
What are the 7 VPN services found
It appears seven Hong-Kong-based VPN providers – UFO VPN, FAST VPN, Free VPN, Super VPN, Flash VPN, Secure VPN, and Rabbit VPN – all share a common entity, which provides a white-labelled VPN service. And they were all leaking data onto the internet from that unsecured Elasticsearch cluster, VPNmentor reported.
What are the two most commonly used VPN protocols
6 Most Common VPN Protocols1) Open VPN. OpenVPN is a highly secure and very popular protocol commonly used by many VPN providers.2) Secure Socket Tunneling Protocol (SSTP)3) Internet Key Exchange Version 2 (IKEv2)4) Wire Guard.5) Point-to-Point Tunneling Protocol (PPTP)6) Layer 2 Tunneling Protocol (L2TP)
What are ports 80 and 443 typically used for
Port 80 is used for http (unsecured web traffic). Port 443 is used for https (secured web traffic).
What VPN uses port 500
IPSec VPN
IPSec VPN. IPSec VPN is a layer 3 protocol that communicates over IP protocol 50, Encapsulating Security Payload (ESP). It might also require UDP port 500 for Internet Key Exchange (IKE) to manage encryption keys, and UDP port 4500 for IPSec NAT-Traversal (NAT-T).
What ports for SSL VPN
TCP port 443
The default protocol and port for Mobile VPN with SSL is TCP port 443.
Is port 1723 TCP or UDP
Commonly used to provide remote access to mobile devices, Point-to-Point Tunneling Protocol (PPTP) uses TCP port 1723 for key exchange and IP protocol 47 (GRE) to encrypt data between peers.
What protocol does VPN run on
Many VPNs use the IPsec protocol suite to establish and run these encrypted connections. However, not all VPNs use IPsec. Another protocol for VPNs is SSL/TLS, which operates at a different layer in the OSI model than IPsec. (The OSI model is an abstract representation of the processes that make the Internet work.)
Which protocol is used to connect VPN
Point-to-Point Protocol (PPP) is used to encrypt the data between the connection. PPTP is one of the most widely used VPN protocol and has been in use since the early release of Windows. PPTP is also used on Mac and Linux apart from Windows.
What is the port 3306 used for
Port 3306 is the default port for the classic MySQL protocol (port), which is used by the mysql client, MySQL Connectors, and utilities such as mysqldump and mysqlpump.
What is the difference between port 3389 and 443
HTTPS protocol provides encryption between your computer and the remote desktop. It uses port 443, which transmits data through a Secure Sockets Layer (SSL) tunnel. This means that port 3389, the port used for Remote Desktop connections, is blocked to enhance network security.
What is the number 1 VPN service
ExpressVPN retained CNET Editors' Choice Award for best overall VPN after its 2023 review. It maintains its position among other virtual private network services thanks to its dedication to privacy and strong speeds. Surfshark is a close second among our picks.
What are two major VPN types
Types of VPNsSite-to-Site VPN: A site-to-site VPN is designed to securely connect two geographically-distributed sites.Remote Access VPN: A remote access VPN is designed to link remote users securely to a corporate network.
Is VPN TCP or UDP
TCP is more reliable, but there are many uses where UDP is preferred and this is usually the default protocol on most VPN services. UDP is a great option if you are gaming, streaming or using VoIP services.
What is port 8080 vs 443
HTTPS protocol transfers encrypted data to port 443. On the other hand, as HTTP transfer data as plain text, port 80 or 8080 can receive them on the web server. The port number identifies each protocol and allows more organized communication. As a result, port number 8080 is only recognizable for HTTP protocol.
What is port 8443 used for
Port number 8443 is an alternative HTTPS port and a primary protocol that the Apache Tomcat web server utilizes to open the SSL text service. In addition, this port is primarily used as an HTTPS Client Authentication connection protocol.
What are ports 500 and 4500 used for
IPSec VPN. IPSec VPN is a layer 3 protocol that communicates over IP protocol 50, Encapsulating Security Payload (ESP). It might also require UDP port 500 for Internet Key Exchange (IKE) to manage encryption keys, and UDP port 4500 for IPSec NAT-Traversal (NAT-T).
What is TCP port 500 used for
As the port for IKEv2, L2TP, and IPSec, port 500 is quite popular for establishing VPN connections; it's also popular for establishing connections in web browsers and operating systems.
How do I find my VPN port number
How do I find the port number of a specific IP address All you have to do is type “netstat -a” on Command Prompt and hit the Enter button. This will populate a list of your active TCP connections. The port numbers will be shown after the IP address and the two are separated by a colon.
Why use port 8443 instead of 443
The key difference between HTTPS port 443 and port 8443 is that Apache Tomcat uses 8443 to open SSL text service to avoid conflicts, whereas 443 is a web browsing port meant to secure data transmission between web browsers and servers.
