Hi All, I have squid 3.3.8 configured as a transparent proxy. My router is redirecting web requests on port 80 to the squid box on port 3128. The problem is that the request is returned url could not be retrieved. My configuration file is below. I am hoping that some one can take a look at it and help me resolve this issue. The proxy server works when I direct traffic to port 3128 using the browser. Router script is below the config file. Thanks
