For port 443, you'll need to set up a streamSettings section to handle TLS encryption, using a valid domain or IP address and also your SSL certificate.
Obtain SSL Certificates: Because you are using port 443, you'll need an SSL certificate. You can get these for free from Let's Encrypt. The certificate verifies the identity of your server, making your traffic look even more legitimate.
Firewall Configuration: Make sure your server's firewall allows traffic on port 443. This is usually done through your cloud provider's control panel or using tools like ufw or iptables if you are on Linux.
Client Configuration: Install a V2Ray client on your device. Then, configure it to connect to your server using the domain name or IP address, port 443, and the settings you specified in your server configuration.

Advantages of Using Port 443

Stealth: Blends in with HTTPS traffic, making it difficult to detect and block.
Security: Uses TLS encryption, adding an extra layer of security.
Compatibility: Works well with most networks and devices.

Potential Challenges and Troubleshooting

Certificate Issues: Make sure your SSL certificate is valid and properly installed.
Firewall Problems: Double-check your firewall rules to make sure they allow traffic on port 443.
Configuration Errors: Carefully review your V2Ray configuration file for any typos or mistakes.

Exploring Alternative Ports: 31471, 21475, 34987, and 23553

So, while port 443 is a great option, sometimes you might want to try other ports. This is where ports 31471, 21475, 34987, and 23553 come into play. Using different ports can provide several benefits, such as better performance in certain network conditions or the ability to evade more sophisticated censorship attempts. Let's delve into why you might consider these less common ports.

The Rationale for Using Uncommon Ports

Why bother with ports that aren't as popular as 443? The primary reason is to avoid detection. Censorship systems often focus on blocking traffic on common ports associated with VPNs or proxies. By using less common ports, you can fly under the radar. Also, less crowded ports might sometimes offer better performance, although this can vary depending on your network. The goal is to make your V2Ray traffic look less suspicious and improve your overall experience.

Configuration Details for Each Port

Port 31471: This port is a good choice if you're looking for a less-used option. In your config.json file, set the port in the inbound and outbound settings to 31471. Ensure your firewall is configured to allow traffic on this port. No special configuration is usually required, making it a straightforward option.
Port 21475: Similar to 31471, port 21475 offers an alternative. Make sure you update the port settings in your V2Ray configuration to 21475. Also, update your firewall settings to allow traffic through the new port. This port can be used in place of 31471 if needed.
Port 34987: This is another alternative port. This port may offer different network behavior. Make sure to configure your V2Ray settings and firewall to allow traffic through port 34987. Use this port as an alternative to the other ports.
Port 23553: This is the last in this set of ports, which is another choice that can be used to bypass restrictions. The setup steps remain consistent: update the port number in your V2Ray configuration file and ensure your firewall allows the traffic. This port is useful to change when others are blocked.

Firewall and Security Considerations for these Ports

Whenever you use non-standard ports, you have to ensure that your firewall settings are correctly configured. This means opening up the ports on your server's firewall to allow incoming traffic.
