<p class="MsoNormal">Hi Folks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am brand new to squid, my main work areas being storage, VMware and linux. I was asked to setup a forward proxy server on a CentOS VMware guest. I initially chose nginx, which seemed to work fine most of the time but about once a
week would stop working and require a reboot to get going again. When I tried to get assistance with the nginx issue, I was told it was not supported as a forward proxy, and I should use squid.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I started over, CentOS 7, squid 7:3.5.20-15.el7_6.1, and kept more or less the default config. In my config I commented out all the possible internal networks except the ones in use, and added<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">acl GOOD dstdomain .vertexsmb.com<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The use case is as follows:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our Order Entry server will request a tax calculation from a Vertex cloud server by sending XML code (below) through the squid server. There is a firewall between us and the Vertex cloud.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The squid server returns the expected display when I put the test url into the browser on the squid server. So the firewall is allowing squid to vertex. When the Order Entry server sends the XML code, however, we get an error returned
to the server making the request (below also). I have also included the error I see in wireshark on the squid server when watching the transaction. Any help would be greatly appreciated.
