These ports are typically opened by default on a private local (internal) network; however, some network administrators may implement a policy that blocks ports without specific approval.
In most current workflows, only the following ports will generally be needed by the client workstations:
- 80 TCP/UDP
- 111 TCP/UDP
- 445 TCP
- 2054 TCP/UDP
- 8090 TCP
- 8091 TCP
- 8577 TCP/UDP
