I need to activate windows through an external KMS server.
my network (roughly):
PCs (win7 machines) --> Windows 2008 with Forefront TMG acting as VPN-Gateway ---> CENTOS IP-Tables Gateway to Internet --------> Internet -----------> KMS-Server
I have configured DNS so that workstations use the Forefront Server to connect.
I opened the relevant ports and redirecting through NAT on the Internet-Gateway.
But the connections fail and I even cannot establish a VPN connection from the Forefront server.
I think the reason is, that the DNS says to use the Forefront server as gateway.... and so the Forefront server itself uses "itself".
I tried adding a route on the server to point to the Centos-gateway..but on that gateway, I can see packets arriving with:
Source: /ip-of-forefront/ Destination: /ip-of-forfront/
So I assume, I created a circular route...and cannot connect to the KMS-Server through VPN.
Please advise... Hopefully my problem is understandable.
