Ok Tom, help my understand this.

What I've done is create a computer object and assigned my ISPs DHCP server
IP address. Then I double clicked on the "Allow DHCP replies from DHCP
servers to ISA Server" which brings up the System Policy Editor dialog box
focused on DHCP. From there I clicked the From tab and added to the current
list my DHCP computer object, "ISP DHCP".

So the way the rule reads now is as follows
Protocol: DHCP (replies)
From/Listener: Internal, ISP DHCP
To: Local Host

Do I understand this correctly?
