I think I have found a workaround for this. Today I got a call from surf
control regarding the issue and fire fox clients by passing the filter.
Accidentally I removed the proxy settings and set the internet explorer to use
automatic detect settings. Guess what, even IE was bypassing the filter. What a
nightmare. So I thought the case would be this control software's are not able
to filter any direct access to internet, basically if the browser is not set to
isa and port 8080, they won't be seen by filter and of course by pass the
filter. On the other hand I needed my firewall client to be on as I wanted to
do some application policies based on users. So we came up with this idea that
set the browser setting using group policy to go through isa and port 8080.
Also going to networks, right click on internal and hit properties. Go to
firewall client tab and get rid everything except the enable firewall client
for this network. In this case users can still use applications based on
firewall client and also any direct access or automatic with any browser
including fire fox and IE will get a big deny from ISA. This will force them
either go through proxy and get caught or do nothing.
I also appreciate any help or comment on this method. Also if there is anyway
to force a direct connection to go through proxy and get filtered
Hope this helps

Adding in "Firefox/" into the filters helped, just got my first complaint from
a Firefox fan about it not working anymore.
* Error Code: 502 Proxy Error. The request was rejected by the HTTP
filter. Contact your ISA Server administrator. (12217)

Yes
I noticed the same thing. You can block IE not everything except IE
