Adding a new NIC to Forefront TMG 2010

Hi there,

after installing Forefront TMG 2010 we now want to configure ISP-Failover. We choosed the configuration as Edge Firewall, so there is one internal and one external NIC. It is a virtual server on VMWare ESX 4.1.

The problem is that we need another external NIC for the second ISP. We have added a new NIC to the server, but Forefront does not recognize it. There are only the both initial NICs available.

How can we add the third NIC to the configuration of the TMG?

Best regards, Ralph

Just to understand better,
You added a Hardware NIC to the Host Server.
Then you Need to add a Virtual NIC to the Virtual TMG. This Virtual NIC needs to be associated to the Hardware NIC.
Is this correct?

No we only added a virtual NIC to the virtual server, not to the ESX host. The OS Windows Server 2008 R2 recognizes the card, but Forefront does not.

I remember that I needed two restarts to make this Work.
One to install the Virtual NIC and the Second for TMG.
