Hi Jim,

I just can't figure out why that one nic with 172.0.0.1 plugged into a
switch can't ping another computer
172.0.0.2 in the same subnet also on that switch.  I'm getting closer.
I keep a reading and I'm making wonderful discoveries
Along the way, I like 2004 thus far!  I have the 2 card machine done
quite well.  I think that it's the addition of the other 2 nic cards
that is throwing me off track. Or maybe those Olympic sites you sent me
to did that I'm not sure. <grin> Gladiator? Yup he was.

Joseph

Hiya Joe,

If all networks are local to the server, route add is irrelevant.  The
IP stack already knows them.

Hi Thomas,

Yup, it's me asking questions!  I'm discovering that with ISA 2004
"ROUTE ADD'S" might not be needed is this true? I've been reading the
docs about setting up subnets and such and your VPN in a back to back
setup, where you had Used 10, 172, 192 and 192 as another subnet.  I'm
looking where ISA sets up the process to all you to ping all those nics.

Switch 1 for example

Has 172.0.0.1 from the multihomed machine
And 172.0.0.2 from a different machine.  When on 172.0.0.2 I'm unable to
ping the 172.0.0.1 machine. 

I've learned a lot this week about ISA 2004 from the groups and reading.
Just did not have enough time to spend on 
Getting this new network in place before I fly tomorrow. Guess I'll have
to live with old setup until I get back :(.

So with this article:
http://www.isaserver.org/articles/2004multdmzp2.html what "ROUTE ADD'S"
would be used? It also seems that The route function within ISA is
different then "ROUTE ADD'S" I did not really want to setup lots of
"ROUTE ADD'S" unless it was necessary. I have my *.cmd file ready to
apply or remove the entries when I get just one machine pinging.

Thank you,

Joseph
