How does ISA box get to see the world? by Magellan
Posted: 1 Nov 01

The problem is my ISA server box (which has been secured) simply couldn't see the world whereas all my clients were merrily surfing, using ftp and so forth.
As Microsoft had warned, ISA box cannot be made a client of itself...very true indeed. However there are these packet filters which can go a long way to straighten things up.
It demands a packet filter which allows tcp outbound 80 from dynamic or any port. So here it is....
Name: Allow Port 80
Filter: Custom
IP Protocol: TCP
Direction:Outbound
Local Port:All Ports
Remote Port:Fixed Port
-do- number:80
This applies to default ip addrs(s) in local computer tab and to all remote computers in remote computer tab.

Hope this helps future ISA amateurs.
