>I've found that you can't publish services to the DMZ using the Server
Publishing Rules because you can't have a non routable IP set as the
external interface on ISA server so this option won't work considering that
my dmz interface is 10.112.1.1.

I have plenty of server publishing rules using a private IP on the external
nic, and it's working fine.

I've found that you can't publish services to the DMZ using the Server
Publishing Rules because you can't have a non routable IP set as the
external interface on ISA server so this option won't work considering that
my dmz interface is 10.112.1.1.

Thanks for the suggestion though...I thought we were rockin' for a second.

I am interested also with this problem but i had no time until now to
experiment except like you to open the dmz tunnel with bewan and zyxel
boxes.

I was only thinking something else : to allow traffic means for example for
your remote clients to get access to some services inside your main intranet
: why not publish these services to the DMZ ? in this case while they reach
the dmz they should be able to reach what they need. It is clear that we
can't open ISA in such a way that the firewall would be useless. The same
outside with destination sets.

Let me know what you will finally decide.

I'm trying this question again, see if I can get an answer this time.

I'm trying desperately to get the ISA to allow traffic to pass through it
that is destined for another network.

I have a linksys vpn router hanging off of the ISA's dmz.
VPN router's LAN(DMZ) address is 10.112.1.3
VPN router's WAN address is 140.168.42.60

The remote network also has a linksys vpn router.
VPN router's WAN address is 68.80.66.170
VPN router's LAN address is 10.116.1.1

After establishing the tunnels successfully:

I can successfully communicate with hosts on the ISA's dmz from the remote
network and I can successfully communicate with the remote network from the
hosts on the ISA's dmz.

I can communicate successfully(throughr the ISA)from the hosts on the ISA's
dmz with clients on the local network behind the isa (10.128.0.0).

I cann't communicate with the clients on the local network behind the ISA
from the remote network.

I can't communicate with the clients on the remote network from clients on
the local network behind the ISA.



How do I set the ISA to allow the traffic destined for the local network
(10.128.0.0) from the remote network (10.116.1.0) pass through it and vice
versa?

Any help would be greatly appreciated!
