I'm trying work around an issue with the firewall by using Application Request Routing/Web Farm.
Configuration:
2x Windows Server 2012 R2 configured with IIS
Both identical configuration hosting several websites
Firewall configured to round-robin distribute between both websites
Firewall doesn't support a "health-check" so it will direct to a server that is down for whatever reason
My thought was to use ARR/Web Farm to handle where a server is down, e.g. direct traffic accordingly.
Followed the steps:
1. Installed ARR on both servers
2. Created a "Web Farm" and added both servers by name
3. Configured the Heath to use a site address. Tried both the dedicated "health check" built into the app and also the home page
4. Testing of the health check fails with a 404 error for both servers - note that the health check resolves fine on each of the servers locally when tried from a browser
Not sure where to go from here. Any ideas?
