How to bypass windchill services from Windows firewall settings?

[hn.a]

If I Enable Windows Firewall on Windchill replication Server, There will be NO Handshake between Master server and Replication Server.

Is there a way to bypass the Windchill services through Windows Firewall recommended settings when it is Enabled?

Communication between the master and replica servers is done over HTTP/HTTPS. You just need to open whatever port apache is listening on from the firewall (usually 80 for HTTP or 443 for HTTPS), and there should be no communication issues between the master and replica.
