    Hi ,

    The netsh advfirewall firewall add rule command is used to adds a new inbound or outbound firewall rule that filters traffic by allowing or blocking network packets that match the specified criteria.

    You can see the syntax below:

    There is no parameter about Custom rule type.

    Thanks.
    Is there one example to modify one existing rule by adding more Remote IP (or range) to the rule?
