I have followed below links to install TMG Enterprise. TMG is planned to deploy behind hardware firewall as back-firewall topology. First link is most suitable for our environment.

1 dedicated Windows 2008 Ent SP2 for EMS with 1 NIC.
2 Windows 2008 Ent SP2 for TMG firewall Servers with 3 NIC each, 2 are configured as Internal and External while third is not configured yet for Inter-Array Communication. TMG service packs are not installed yet. NLB is configured, in Windows and not yet in TMG.

I have some confusions and queries.

1. In some articles, TMG servers are configured and then join to Array, while others first join TMG Servers to Array and then configure. Which is correct way to do?

2. I have created a new Array in EMS with default policy. After that i have joined both TMG servers to the Array created in EMS by selecting option Join an array managed by an EMS server.

I did not use Getting Started Wizard in both TMG firewall servers after installation completed. Assuming that wizard would be available in EMS for configuring network topology, firewall and web configuration. Now I cannot see Wizard in EMS. From which TMG server do i have to run the Getting Started Wizard to configure TMG. Should it be run on first server only or both?

3. I have single site but still i'm using EMS and TMG NLB for high availability. For single site does it require/recommended to choose Join a standalone array managed by a designated array member (array manager) As many articles point to this option. Which array option has advantage considering HA?

4. Can Inter-Array NIC be configured after installing TMG or do I need to uninstall TMG for modification or any other option or ignore 3rd NIC totally for Inter-Array communication?

Thanks all for reading this post. Kindly assist.
