The problem is that you have no choice but to use the proxy. If they are
blocking port 80, nothing you do on your local system will change that. The
only other option really is to use a different proxy.
The difference between the two is implementation. I don't know what
products are used in either case, but having the filter happen
"transparently" is better, in my opinion, since you don't have to configure
proxy information in your clients (which is a real pain if you use more than
just a web browser, like automatic software updaters). In either case, you
run the risk of the filterer being your bottleneck during peak times.
On a personal note, I had a very, very bad experience with eFortress when
they bought ITS. The tech support was clueless and the filter was dropping
50% or more of the packets during peak hours. I switched to Burgoyne and
didn't have any problems with their services. For some reason, when I used
PAP authentication, I got an IP address that didn't have port 80 blocked,
where if I authenticated with a login and password (script approach), port 80
was blocked. This might have been an oversight on their part with my
account, but I didn't complain :)
