Re: [SQU] transparent VS normal proxy

Just thinking that alot of the problems with transparent proxies on this
list, are due to the way they work, what with having to configure the
router, and all... maybe a better description is needed on the FAQ? but then
routers are often very different so it would be hard to write a detailed
description on how to set up transparent proxies... but i think that the FAQ
needs some more detail on transparent proxies... but it is a huge effort.
We dont run a transparent proxy here, but instead force our users to use a
proxy by running filters on our dial-in unit... that works really well, a
user can only access local sites (like our help site) without a proxy set..
we get a couple of calls, but it is easy to figure out what is wrong...
