Which command allows configuration of a non-standard firewall port?

The choice that can properly configure a non-standard firewall port is based on the syntax that supports the specification of multiple non-standard IP addresses alongside the defined port range and the direction of traffic.

In this context, allowing non-standard firewall addresses indicates that the command accommodates connections that are not typically permitted by default configurations. Specifically, this option specifies the IP addresses that are allowed through the firewall, alongside the defined non-standard ports (7937 and 7938) as inbound traffic over TCP. This flexibility is vital in scenarios where the organization may need to use ports outside of the standard ranges for various applications or services.

This command's structure shows that it directly addresses the need for specifying both the allowed IP addresses and the exact non-standard ports, making it effective for configurations that require humane adjustments to firewall policies without compromising security or functionality.

The other options do not fit the requirement for configuring non-standard ports because they either reference ranges that include standard ports or emphasize blocking or enabling rather than allowing specific new configurations for already-defined rules.
