Hi Thomas,
When I tried to load VPN on my internal ISA machine, I wasn't able to start
the RRAS service. I looked at all the KB articles out on MS and wasn't able
to come up with a solution. Except maybe rebuilding that box. I'm still
looking for a way to reinstall RRAS without having to do that. Then I can
see if the double NAT thing will get me stuck. Right now just can't gain
access through both firewalls to make a connection to a client located in CA
via VPN. If your time has been anything like mine..None I would appreciate
any other ideas that you or others have on this list.
Thank you,
Joseph

Hi Joseph,
The DNS comment was just sort of a "oh, by the way", in that if you have
servers on the DMZ that need to resolve either DMZ host names or published
servers on the internal network, you can put that DNS server on the internal
network and publish it. That's how I usually handle things when doing the
split DNS thing.
Outbound VPN access should not require the same setup, as you can use the
PPTP passthrough feature to access external VPN servers. IIRC, the double
NAT doesn't cause too much of a problem ;-)
HTH,
Tom

Hi Thomas,
I've been re-reading the VPN in a back to back setting and have a question
about the following statement and how it applies to DNS.
http://www.isaserver.org/tutorials/Configuring_VPN_Access_in_a_Back_to_B
ack_
ISA_Server_Environment.html
"One other thing you might want to do is configure a DNS server publishing
rule on the internal ISA Server, if you wish the DMZ hosts to use a DNS
server on your internal network. This is not required by the back to back
ISA Server VPN configuration, but it's something you should think about."
I'm not sure if you meant that it is a good thing to publish the DNS server
on the internal network or not and just looking for clarification on that
issue. Also, would this be the same setup to VPN out through the back to
back setup? From my internal network through the internal firewall through
the dmz and out through the external vpn?
