The ProtonVPN app's default port is 1194 for UDP (which is the default port for OpenVPN) and 443 for TCP. However, the app is configured to work with other ports for both UDP and TCP.

Set Up Your VPN on Android Devices
On Android, you need to first install the strongSwan VPN Client app. Then, copy the P12 file inside the Configs folder over to your Android device and open it in strongSwan. Follow the directions from there to set it up. If you need help, this guide will walk you through each part.Unlike a firewall, a VPN doesn't allow you to establish data packet and network port restrictions on your computer. While some VPNs might feature a Killswitch that cuts Internet access if the VPN connection fails, that is not the same thing. Lastly, a firewall will not help you bypass geo-restrictions online.
Windows comes with the built-in ability to function as a VPN server, free of charge. It does this by using the point-to-point tunneling protocol (PPTP) and can be confusing to set up if you're not too tech-savvy.
L2TP (Layer Two Tunneling Protocol) VPN - an extension of PPTP often used with IPSec to establish a VPN. Note: OpenVPN traffic can be hidden by forwarding just port 443 TCP in your NAT router/firewall instead of using teh default port 1194 TCP/UDP.
You cannot change the port number for the Windows built-in VPN. The most you can do is use port-forwarding on the router. I believe that this is possible if you use OpenVPN instead of using Windows for both server and client.
How to set up a free VPN
- Choices, choices… To choose a free service, we started by looking at TechRadar's recommended list of best free VPNs.
- Going with the free plan.
- Enter your email.
- Confirmation.
- Configure your credentials.
- Download the software.
- Fire it up.
- Get connected.
The Windows VPN software is the simplest option for those who want something that just works without fuss, and it boasts the fastest average download speed of any VPN we've tested so far—great for P2P filesharing and streaming.
Android OpenVPN Connect Setup
- Open the Android Playstore.
- Search for OpenVPN Connect and click "Install.
- Click "Accept"
- Open your browser and navigate to
- Choose a server you would like to connect to by clicking on a location, the file will download.
Steps
- Enter the port. Type the port you want to check (e.g., 22 for SSH) into the "Port to Check" box.
- Click Check Port. If the port is open and available, you'll see a confirmation message. If not, you'll see a message that says "Error: I could not see your service on (your IP address) on port (the port number)."
Which Ports Are Usually Open By Default?
- 20 – FTP (File Transfer Protocol)
- 22 – Secure Shell (SSH)
- 25 – Simple Mail Transfer Protocol (SMTP)
- 53 – Domain Name System (DNS)
- 80 – Hypertext Transfer Protocol (HTTP)
- 110 – Post Office Protocol (POP3)
- 143 – Internet Message Access Protocol (IMAP)
- 443 – HTTP Secure (HTTPS)
A port number is a 16-bit unsigned integer, thus ranging from 0 to 65535. For TCP, port number 0 is reserved and cannot be used, while for UDP, the source port is optional and a value of zero means no port.
How to find your port number
- Start your command prompt.
- Type ipconfig.
- Next type netstat -a for a list of your various port numbers.
To determine your computer's private IP address, if you're running Windows, click Start, then Run, then type cmd and press Enter. That should give you a command prompt. Type the command ipconfig and press Enter -- this will show you your private IP address.
Click the "Advanced" tab, and then select the "Network" tab. Click "Settings" to open your proxy server configurations. View the section labeled "Manual Proxy Configurations." This lists the IP and port addresses of your proxy server.
A port number is the logical address of each application or process that uses a network or the Internet to communicate. A port number uniquely identifies a network-based application on a computer. This number is assigned automatically by the OS, manually by the user or is set as a default for some popular applications.
But in some situations it is desirable to configure the OpenVPN daemons to listen on a specific network interface only. You can also change the ports that the OpenVPN daemons listen on here, but we normally recommend not changing these unless there are unique circumstances.
Port blocking
By default, OpenVPN uses port 1194 (UDP, although this can be easily changed to TCP). Other VPN protocols use different ports. A simple but effective way to block VPNs, therefore, is to use a firewall to block these ports.Ports used for VPN Protocols
- For OpenVPN, we allow connections via TCP or UDP protocols on ports 443 or 1194.
- Both PPTP and L2TP need the PPTP & L2TP pass-through options in the firewall/router's management interface to be enabled (if applicable).
- Both IPSec and IKEv2 use UDP port 500.
- SSTP (Available via our windows client only) uses TCP port 443.
OpenVPN is a relatively new and highly configurable protocol. ExpressVPN's version supports both UDP and TCP ports. UDP stands for User Datagram Protocol. Though it can be configured to run on any port, OpenVPN runs best on a UDP port, which is generally faster.
OpenVPN config files are usually located in /etc/openvpn and usually named *. conf . server. conf is canonical; client config filenames are usually like <client name/>.
Install OpenVPN
- PiVPN needs a STATIC IP ADDRESS to function properly.
- If you have more than one network interface, Choose any one to configure it.
- PiVPN will not configure Static IP address if you're not using Raspberry Pi device.
- Next, choose a local user that will hold your ovpn configurations.
Version 3 and newer: You can select TCP or UDP in the VPN settings. Tap the cogwheel located to the right of the currently selected server and change Protocol from UDP to TCP. Make sure you tap Apply so that the setting takes effect (and the connection (re)starts).
The Root AP assigned IP address to your router. In such case, you have to set up
Port Forwarding, NAT Server, or Virtual Server on the Root AP to connect to your router over Internet via a
VPN.
How to set up VPN server with port forwarding?
| VPN server | Port |
|---|
| PPTP | TCP 1723, Other 47 |
| OpenVPN | UDP 1194 |
| IPSec | UDP 500, UDP 4500 |
Once you have downloaded the configuration file, you can edit it with a text editor (I advise you to use Notepad++): open the file ". openvpn" for windows" and ". conf" for Linux and look for "proto udp" (3rd line). Change it to "proto tcp" if you want to switch to TCP.
