Windows 2012 R2 Data Center NLB IIS URL Rewrite
Windows 2012 R2 Data Center Web Farm IIS
Meraki MX 60

I have two public facing web sites mymusic.com mysports.com using port 80

internally I can access both sites using the virtual ip address 10.10.10.171 of the NLB servers

On my Meraki I changed the firewall port forwarding rules protocol TCP  public port 80 Lan IP 10.10.10.171  local port 80

I am unable to browse the site externally using the NLB virtual ip address

If in my meraki I change to the physical ip address of one of the Web Servers in the farm that works.

I did a netstat -a and port 80 is listening o both the NLB servers and the Web Farm Servers

could it be the URL rewrite rule ?

Any ideas?

thank you

Tom
