This page helps system and firewall administrators make adjustments to the firewall rules, as appropriate when communication with Remote System Explorer or Remote Debug is hampered by firewall constraints.
In most cases, you may specify a numeric range for ports to be assigned as listening ports. Ports that connect to those listening ports are assigned by TCP/IP, generally from a pool of ephemeral or dynamic ports.
It is recommended that you avoid specifying ranges that overlap with other ranges.
See Example of firewall rules on a workstation for example configurations.
