Ok, so here is my approach to bindings in IIS using Web Farm Framework 2.x. I have seen several ways of doing this, but all involved setting up replace rules for WFF and I didn’t want to mess with that.
What I do is, on my controller webserver, I add all of the bindings for each of the machines. In the drop down menu for IP address, you can manually type in the IP, and the server will let you add anything, regardless of it being assigned to the machine. Then IIS will accept the requests for which it has an assigned IP address, the rest will be there but not do anything. These settings will propagate to all of your servers in your WFF Server Farm, and you will be able to maintain your single point of administration for IIS.
Thanks for the tip!
