Tidying up ISA 2004

[eejit]

My network runs fine, but I'd like to get rid of some "errors".
I have an ISA2004 as the default gateway.
Of course, an ISA limits all types of traffic by default until you open it up. How do I open up the general internal windows infrastructure traffic?
For example, when I do a netdiag I get this error:

Default gateway test . . . . . . . : Failed

    [FATAL] NO GATEWAYS ARE REACHABLE.
    You have no connectivity to other network segments.
    If you configured the IP protocol manually then
    you need to add at least one valid gateway.

What do I need to open up/reconfigure to make the gateway reachable again?

Cheers.

Hi,

You need to open up the ping traffic for the test you done.

Thank you sir. Virtual pint on it's way. Worked perfectly.
