I am trying to intercept traffic on port 8000. For example my application is running on abc.com:8000. I am unable to intercept this traffic on burp suite. How can I intercept this traffic in Burp?
In the screenshots below, I've assumed you want to intercept traffic at port 8080 (which is not the default port for the http protocol).
Start burpsuite and enable it to start intercepting network traffic from your machine by clicking on the "intercept"button as shown in the screenshot here:
If you have traffic flowing via some other port number then change to it from 8080. Otherwise, you need to use the port no which you have chosen. In case you need the proxy for other protocols such as intercepting SSL traffic, then enable proxy for other protocols too.
As soon as you change the proxy config, all network traffic will start appearing in burpsuite for interception and modifications.
