I have just recently put Untangle up between my mail, web, & DNS server and the internet. I noticed that when the Untangle Firewall is on clients get very slow loading of the OWA page for example. When the firewall is off it's faster.
When I have someone load the OWA page for example, ports 443 and 80 are open but yet when they hit enter the bars for block and pass shoot up, and there is nothing in the logs.
I have all the ports I want open and the default rule is to block. Why is it so slow when the firewall is enabled?
