Hi Marvin, 
 
The issue with dynamic addresses on the external interface is that you
will be assigned the ISP's DNS server on the external interface. There
are rare circumstances where this can cause a problem. Even though rare,
why not make them just not happen? Force the external interface to use
your own DNS server, which can resolve both internal and external
network names.
 
If you had a static address bound to the external interface, you can
leave the DNS server setting blank.
 
HTH,
Tom

        Hey Tom

         

        Too late. The interface configuration tutorial and the quick
start has me spinning in circles. I'm just thankful John is in a patient
mood tonight. :-)

        Hi Marvin,

         

        Don't be confused. Just do what I said in the article and it
will work.

         

        HTH,

        Tom

                http://www.ISAserver.org

                Misprint and understanding because the quick start
provides a different suggestion for configuring the external interface
than the "configure ISA server interface settings" tutorial. For dynamic
IP addresses quick start suggests configuring the external as so: 

                Obtain IP automatically

                Use the following DNS server: ISA server IP

                 

                The interface tutorial mentions: 

                IP address: 123.123.123.170

                Subnet: 255.255.255.248

                GW: 123.123.123.169

                DNS: blank

                Advanced: 

                            Uncheck "register this connection's ..."

                            WINS: Uncheck "Enable LMHOSTS lookup"

                            Select: Disable NetBIOS over TCP/IP. 

                 

                Kinda confused on which way to go with this? Trial and
error?
