Configuring Routing Table Entries in the TMG Firewall

image With the ISA firewall, you could add and remove routing table entries using the Route Add and Route Delete commands. We’ve been doing it that way for years and years – it’s tried and true, we know how it works, and it always (almost) does what it’s supposed to do.

So what’s up with the TMG firewall? Have you found that you added a routing table entry during setup, and then wanted to remove a route? Did you notice that when you used the Route Delete that it still showed up in the routing table?

Whoa.

What’s up with that is the fact that you need to use the TMG firewall console (both MBE and 2010) to make the routing changes.
