Add a rule to the TCP or UDP port table. Port numbers are used by TCP or UDP to identify sending and receiving applications. Some common ports include HTTP (80), TELNET (23) and SMTP (25).
| Parameter | Description |
|---|---|
| Name | User-friendly name associated with the TCP or UDP port range. |
| "Any Remote IP address" or "Specify Remote IP address and/or mask" | Specify whether the rule should be applied to any remote IP address or to a specific remote IP address/mask pair. |
| Remote IP address | IP address of the remote machine or subnet.
This field is editable only if "Specify Remote IP address and/or mask" is selected. |
| Remote IP mask | IP address mask of the remote machine or subnet.
This field is editable only if "Specify Remote IP address and/or mask" is selected. |
| Starting port number | First UDP or TCP port in the range. |
| Ending port number | Last UDP or TCP port in the range.
The ending port number value should be equal to or greater than the starting port number. |
| Protocol | Specifies whether the port protocol is UDP, TCP or both. |
| Inbound action | Specifies inbound action for network connection. The ignore action is useful when you want a 'UDP/TCP Port' rule to apply in only one direction. For example, setting a rule for HTTP (Web) port 80 to deny inbound and ignore outbound will always block Web connections in the inbound direction, but will let a more generic matching rule or the default action determine the action for outbound Web connections. |
| Outbound action | Specifies outbound action for network connection. The ignore action is useful when you want a 'UDP/TCP Port' rule to apply in only one direction. For example, setting a rule for HTTP (Web) port 80 to deny inbound and ignore outbound will always block Web connections in the inbound direction, but will let a more generic matching rule or the default action determine the action for outbound Web connections. |
