Port Forwarding – Binatone port forward settings – Access local xampp using static IP

Leave a comment

Step 1: Open your system comment and type “ipconfig”.

Step 2: Check your system “Default Gateway” and “IPv4 Address” using comment “ipconfig” as like below image.

Step 3: Open your router settings page using Default Gateway. As per my case, use “192.168.1.1” in browser to access the settings page.

Step 4: Go to Port Forwarding settings page and forward the required post to your system. We could use the port based on your need.

Step 5: I need to post the 80, Because I need to access the xampp from remote or through internet. So, my local system xampp running under  port 80.

Step 6: Also, Port Forwarding settings will change based on router. As per my case please find the below image.

Binatone port forward settings
Go to -> Advanced -> NTA -> Virtual Server and follow below settings.

Step 7: All settings DONE. Now testing, Check your system IP. Just type “What is my IP” in Google.

Step 8: For example your IP is 77.777.77.88. While I access through 77.777.77.88:80 OR 77.777.77.88, it will post to local system xampp.
