Here is my situation: I have 1 webserver with Apache & IIS. I have 1 domain (mydomain.com). The reason I have IIS is because I have some ASPs I want to host. Now I'm wondering how to configure Apache to redirect to IIS if it is on a certain subdomain (ie. sub1.mydomain.com) otherwise I will use Apache to process. Now I have setup my virtual hosts to redirect to port 90 for IIS but the problem is that I redirect via a IP (192.168.1.200:90) and it all works fine on my local network but not from the outside. Is there something I'm missing? or is this even possible?
