It is set. 'From' is set to External.
More thoughts? Thanks!

You have to Allow the dhcp option in the SYSTEM policy for the external
ISA interface.

Subject: [isalist] ISA 2004 Standard: loses Internet connectivity (but
an IPCONFIG release & renew fixes this)
http://www.ISAserver.org
Using ISA 2004 Standard off of 2003 Enterprise; I have this linking up
to a Linksys cable modem. Fairly standard setup. Issue: letting the
system run for approx 2+ hours, the ISA system--let alone the internal
clients--suddenly cannot ping any of the DNS addresses nor ping
addresses.
Doesn't end here...
The gotcha is that the ISA server as well as the internal interfaces can
ping the external (Comcast Cable) default gateway. So L2 to the brouter
appears solid and the brouter's L3 interface is still up.
In doing some testing...
I cannot simply do an IPCONFIG /renew; I found a simple IPCONFIG release
and renew fixes the issue on the ISA server and everything is up and
going again.
My concern is...
This shouldn't be the MO for the ISA server. It should follow normal
procedures and do a renew for it's IP when it's lease is up. It
shouldn't lose all out connectivity to anything outside of it's external
subnet's L2 broadcast network.
Temporary patch...
I've setup an hourly script; runs an IPCONFIG /release & IPCONFIG
/renew.
This is inapproporiate, yet all I have to run on for now.
Thoughts?
Thanks,
Joe Heinz

The haggis is unusual in that it is neither consistently nocturnal nor diurnal,
but instead is active at dawn and dusk (crepuscular), with occasional forays
forth during the day and night.
