I have two domains and we are looking to build a trust beween two domains.  One is a windows 2008 R2 functional domain the other is a window 2003 funtional domain.  I can ping the IP addresses on the 2003 side from the 2008 side but can not ping from the 2003 to the 2008 domain.  The 2008 domain is running TMG. What is the appropriate config in TMG to allow the trust to happen?

Thanks,

Jeff

No I created a VPN tunnel from one data center to another.  I have the tunnel working.  The issue is that the windows 2008 R2 domain which runs TMG that is joined to the domain can ping the 2003 domain through the VPN site to site tunnel, the 2003 domain can not ping the 2008 domain attempting to get through TMG.
