I replaced our new firewall with ISA Server 2006. In the design phase we installed a new Internet connection so I had the chance to install ISA server on this new Internet connection and try it out before we shout down our old firewall During testing, I had a temporary Internal IP-address on my Internal NIC and everything worked perfect. The day we took down the old firewall, I replaced the temporary Internal IP-address on the ISA with the Internal IP-address from the old one. After that, I was not able to surf the Internet on Http from my Internal Secure NAT clients, but when I disable the Web proxy filter, it starts working again?
I install win 2003 server r2 and the middle of it, Isa server, then I created a rule - all outbound traffic from 192.168.20.6 to an external user settings in IE to a proxy server. 192.168.20.1:8080 Internet does not work as soon turn off the filter web proxy in settings HTTP protocol internet starts working. Prompt where an error.
