NOTE:
The new 64 bit Windows templates have the Windows firewall turned "ON" by default ( which was not the case earlier ). To access OpenEdge Management (port 9090 ) and WebServer (port 8080), users either need to manually add these ports to the Windows firewall exception list or turn the windows firewall off. We’re currently working on a patch to turn OFF the Windows firewall on boot and will soon be releasing it to production.
Please refer to the following links for information on how to turn off the firewall:
