Internet is slow when going through proxy server.

When our Astaro firewall is configured for filtration via AD in our Server 2003 domain, the performance of the Internet is seriously impacted.  When lan settings on IE are set for automatic the performance is fine but when going through the Astaro as a proxy server the performance suffers considerably.  I am using just one security group and if the user is in that group they have unlimited access except nudity.  If they do not fall in the group they have default filtration which prohibits gambling, games, etc.  This would be for students.

Looks like there's a problem with the firewall. When does it slow down? From the beginning or after some use? Does rebooting the firewall help? What firmware version? Updating the firmware might help. See if clearing the proxy cache might help resolve or isolate the problem.

Not sure I can help, but considering the network interfaces, such as Gateways etc.... sometimes just clearing the accumultation in the net, resetting gateways, routers, unplugging and on helps some... sometimes just  multiple reboots helps. Does Astro have any upgrades available or filters you could employ to intersect and resolve these issues?

Just in terms of your firewall, not sure you've looked here, there are a number of issues.
