Hi,

For ISA Server itself, its a Firewall, so do not start surfing the Internet from It.
check this : http://www.elmajdal.net/isaserver/Allow_Internet_From_ISA_Server_Machine.aspx

as for your clients, you need to ask yourself, do you need authentication or not ?

if you do not need authentication then you can set your clients as SecureNet clients.

If you do need authentication, set your clients as either web proxy and/or firewall clients.

HTH,
Tarek

To Set your Client as SecureNet Client, set their Default Gateway to point to ISA Server Internal IP Address.

and on your ISA Server create a new Firewall Policy:

Allow > Protocols> From Internal > To External > ALL Users
