I've followed the guide to get Squid up and rolling as a Transparent proxy. Everything works just fine, I point everyone to the Squid box as the default gateway with DHCPD and then hijack port 80, redirecting it to 3128.
But the users are unable to use the Windows Update service, which fails when "checking for updates".
I've seen a lot of posts about this when googling - but not a single solution. A couple of people, after much frustration did manage to get Windows Update service working, but all they did was post that they had gotten it working and didn't bother to say what they did to correct the problem.
I can post my squid.conf file here if neccessary (it's still pretty basic along the lines of the mini-howto
hereUpon googling, this seems like such a common problem that I would think that there would have been some attention given to it in the FAQs at suid-chche.org or other sites, but I've seen no mention of it.
If anyone can provide some assistance It would be greatly appreciated, and we could perhaps add it to the mini-howto
here.
