>why not publish these services to the DMZ ? 

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!
