Hi Alex,
The ISA firewall team at MS likes to keep you on your toes. Unlikely
most of mathematics, which is a consistent system on which you can
create logical extrapolations, that's not the case with the ISA firewall
(or any other software, in fact).
So, for HTTP you can reach all destination ports for outbound HTTP
For HTTPS, you are limited to 443 by default.
Make sense? If so, you were at the meeting I missed.

Call me crazy and rambling if this makes no sense, but I recall that
there was a restriction on the destination port used for http
connections the first time I installed ISA ever. There is a strong
possibility that this applied only to SSL connections (https) but I do
recall trying to access a webmin server on port 10000 via https and I
was graced with a message saying I was trying to HTTP on a non-standard
port and that ISA would not stand for that crap.

The fix I found involved editing the registry, that's all I remember.

It is probably irrelevant to the current situation, but maybe this will
ring a bell in someone's head?
