In this post I will be installing a TMG Array as a “back firewall” behind a hardware firewall. The Array will consist of two virtual servers, TMG01 and TMG02 which each have 3 NICs. One NIC will be dedicated to the LAN network, accessible internally. One NIC will be dedicated to the DMZ network, accessible to the outside world on a static mapped IP. The third NIC will be a dedicated intra-array communications NIC as per Microsoft’s recommendation.
