I have set up the following mini virtual network of servers:
Role: TMG Array member #1
NIC 1: 10.1.128.1/255.255.0.0 DNS: 10.1.128.3
NIC 2: External Public IP for Internet #1
Role: TMG Array member #2
NIC 1: 10.1.128.2/255.255.0.0 DNS: 10.1.128.3
NIC 2: External Public IP for Internet #2
Role: ADDS server, DNS server
NIC 1: 10.1.128.3/255.255.0.0 Default Gateway: 10.1.128.1 DNS: 10.1.128.3 (self)
Role: EMS Server
NIC 1: 10.1.128.4/255.255.0.0 Default Gateway: NONE. DNS: 10.1.128.3 (self)
DNS Entry for the actual array called "TMGArray" points to 10.1.128.4.
Role: Windows 7 Client
NIC 1: 10.1.128.5/255.255.0.0 Default Gateway: 10.1.128.4 DNS: 10.1.128.3
Independent internet connectivity on the two ARRAY* servers was verified and both ARRAY* servers were successfully added to an array called "TMGArray".
Now, the problem I am having is configuring clients to connect to the TMGArray for internet access, instead of directly to an individual TMG Server (which still works, btw).
In other words, for VM1:
NIC1: 10.1.128.5/255.255.0.0 DG: 10.1.128.1 DNS 10.1.128.3 <-- WORKS
NIC1: 10.1.128.5/255.255.0.0 DG: 10.1.128.4 DNS: 10.1.128.3 <-- DOES NOT WORK
How should I be configuring my client so that it connects to the internet via the TMG Array (EMS) and in SecureNAT mode (i.e. no browser config required)?
All help is greatly appreciated!
