Firewall Settings When Using Hosting Controller Secondary Setup for Windows

If you are using Hosting Controller remote setup which uses DCOM for communication between primary and secondary machine, then you need to open port 135 which is used by DCOM. The firewall between your server and the Internet should be configured as follows:

Deny all incoming traffic from the Internet to your server. Permit incoming traffic from all clients to TCP port 135 (and UDP port 135, if necessary) on your server. Permit incoming traffic from all clients to the TCP ports (and UDP ports, if necessary) on your server in the Ports range 100-5000. If you are using callbacks, permit incoming traffic on all ports (range is 100-5000) where the TCP connection was initiated by your server.
