I use the firewall rules and port forwarding to allow access to an app server from an outside web server. I have 4 app servers and 3 are running w/o issue. The rules are identical except for the destination ip and port number.
IIS and routing and remote access is configured the same as the working machine.
Any ideas as why the port will not open.
source port: any
Destination Port: 1675
Source Interface: External
New Destination: aaa.bbb.ccc.14
