My clients are using a proxy server on their corporation,and I want to set up dev environment for testing development related to proxy issues. So, I want to set up a proxy server which blocks all port 80 requests, unless the request is requested by the proxy server. This is what I tried:

  1. Installing fiddler2 on port 8888.
  2. Setting up two rules on windows firewall:
    • Block all port 80 requests.
    • Allow all requests from fiddler exe.

Then, I opened FF and changed the proxy server to be Unfortunately, the requests from the fiddler are still blocked.

What am I doing wrong?

Is there other program which do that easier?

(Tried also with CCProxy without success).


Found the answer in a great post: https://github.com/mapbox/mason/wiki/Windows:-Simulate-an-enterprise-proxy-on-a-single-developer-machine

  1. Block all the outbound connections on the firewall.
  2. Allow request from fiddler.exe
