<div class="ecxmoz-cite-prefix">check out your access log seeing what
it says. Sounds like you are looking for an AFW from squid. The
ports themselves are defined. You need to make sure the other
ports are opened.<br>
<br>
Your rule tells squid to block the non-allowed sites to the
non-allowed ports. Still sounds like FW function, but with the
domain feature only.<br>

<div>Background (just FYI):</div>
<div>I am trying to setup Squid to control network access from a
local subnet to a select number of domains. I do not need to
bump the encrypted traffic and play man in the middle, I just
need to prevent the servers on the local network from accessing
unauthorized networks. Yes, I know I can do this in the
Firewall, but that is IP based and I am dealing with enough
other companies that maintaining the IP list has become a major
pain. Instead I want to use domains, which I can do in Squid.</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
