Remote access to local asp net core applications from ip address

Introduction

Remote access to local ASP.NET Core applications from an IP can be achieved by configuring the application to listen on a specific IP address and port, and then allowing incoming from that IP address on the network .

Configuring ASP.NET Core Application

To configure an ASP.NET Core application to listen on a specific IP address and port, you can modify the application's launchSettings.json file. Open the file and locate the “applicationUrl” property. By default, it is set to “http://localhost:port”. Replace “localhost” with the desired IP address and save the file.


"applicationUrl": "http://your-ip-address:port"

Make sure to replace “your-ip-address” with the actual IP address you want to use and “port” with the desired port number.

Allowing Incoming Connections

After configuring the ASP.NET Core application to listen on a specific IP address and port, you need to allow incoming connections from that IP address on the network firewall. The steps to do this may vary depending on the operating and firewall software you are using.

Here is an example of how to allow incoming connections on Windows Firewall:

  1. Open the Windows Defender Firewall with Advanced .
  2. on “Inbound Rules” in the left pane.
  3. Click on “New Rule” in the right pane.
  4. Select “Port” and click “Next”.
  5. the desired protocol (TCP or UDP) and specify the port number you configured for the ASP.NET Core application. Click “Next”.
  6. Select “Allow the connection” and click “Next”.
  7. Choose the network types where this rule should apply and click “Next”.
  8. Enter a name and description for the rule and click “Finish”.

Once the firewall rule is , incoming connections from the specified IP address will be allowed to access the ASP.NET Core application running on the local machine.

Conclusion

By configuring the ASP.NET Core application to listen on a specific IP address and port, and allowing incoming connections from that IP address on the network firewall, remote access to local ASP.NET Core applications can be achieved. This enables developers and to access the application from a different machine or network, facilitating testing, debugging, and collaboration.
