Server Image Copy also relies on other Microsoft Windows ports.

Microsoft File Share uses ports 135 through 139 for TCP and UDP communications.

Microsoft Directory uses port 445 for TCP and UDP communications.
These ports must be open on your firewall. Check your Microsoft documentation if you need to modify
these ports.
Hardware ports
You need to configure your hardware so that the Server Image Copy and Microsoft Windows ports
are open. Since communication occurs bidirectionally, make sure you configure both incoming and
outgoing traffic.
There are many types of hardware on the market, and each can be configured differently. See your
hardware reference manual for instructions on setting up your particular router.
