Hardware Firewall recommendations (with content filters

[Scott Warren <sw () shelton org>]

I am researching firewall appliances that have content filters for use  
in our school network.  the criteria is rather simple but seems hard  
to fill:
- We are a Mac shop so interactions with the OS X are important (web  
based admin makes this easy)
- We need to be able to authenticate the user against the firewall via  
our LDAP server.
- We would like to have multiple levels of filtering, more open for  
staff, more restricted for students, even more restricted for  
disciplined students, and no access for anyone not logged in.
- Having an application/script that keeps us logged in to the firewall  
rather than just logging in thru the web page (when you apple-Q a web  
browser, you are not logged in anymore and your non HTTP internet  
traffic gets blocked).
- Realtime reports would also be a plus.

I have taken a look at Barracuda, Sonicwall and Vicomsoft. I am  
looking for some other places to check out.

Thanks in advance!!
