How Many TMG Firewalls will you Need?

One of the most common questions I see in various venues is “how many TMG firewalls will I need for my deployment?”

That’s a good question!

It depends on a lot of things:

  • How many users do you have?
  • What firewall services do you want to provide?
  • Are you doing forward proxy, reverse proxy or both?
  • How are you handling authentication?
  • What level of application layer inspection are you going to deploy
  • And lots more!

You can try to deploy a single firewall and extrapolate from there, using PerfMon to guide your decision. Or you can get a jump start by using the Forefront Threat Management Gateway 2010 Capacity Planning Tool! Get the tool at:
