I have two web servers, one is Win2003 IIS 6.0 and the other is Win2008 IIS 7. I need them to host completely different/separate websites (non-cluster, non-load balance, just two separate servers). Right now I have one single public IP and a basic Linksys router. SHould I:
1) purchase a 2nd IP address and upgrade my router to a model that supports 2 public IP addresses?
2) Install ARR 2.0 on the Win2008 box and point the incoming requests to the appropriate IIS server? (Is this even possible?)
