Problem with the internet browsing, even with only one PC behind the server, I can surf the internet but much slow if I'm not behind the ISA server. However I can download with normal speed (using IDM) and the ping is normal.
I have very simple network: ISA server 2006 SP1 installed on Windows server 2003 2 Network cards ( 1st Wan, 2nd LAN) DHCP service enabled with router and DNS option
in ISA server I add this access roles Allow all outbound traffic from Internal & local host to External Allow DHCP Request Allow DHCP Replay Allow DNS for all network
I don't have internal DNS, nor Web publishing server. Just the server and 1 pc at the internet (for testing)
I know this maybe discuss a lot but I search & tried almost everything, no luck
So far nothing wrong with PC when I tested the browsing on it with no ISA in network. The problem in browsing appear when I put the PC behind the ISA server. I can download with normal speed, and Pages loaded, but much slower than if the pc is connected directly to the internet. Specially for some sites like Facebook.
