Unable to Access Resources Behind TMG after Enabling NLB

NLB is often a source of troubleshooting fun – there are a number of reasons for this, and fortunately that don’t have anything to do with TMG firewall software itself. The reason for this is that the TMG firewall is a layer 3 and above firewall, and NLB works lower in the stack.

Here’s an interesting blog post by Yuri Diogenes on how a TMG admin found that while publishing with a DIP worked fine, publishing using the VIP failed.
