Endpoint Window


An endpoint specifies one end of a connection. IP address ranges are also allowed, along with address groups.

Endpoints consist of an address section and an optional port section. The address can be in any one of various formats, including domain name, IP address and MAC address. Ports are only valid for rules that have either TCP or UDP as the protocol.

Endpoint Fields

All Computers

Filters all traffic regardless of the source or destination computer.

Domain Name

Enter the domain name of the computer to filter. This can be the workgroup name, or the full domain name of a server. Protocol labels such as 'http://' are not necessary for this field.

IP Address

Enter the IP address of the computer to filter.

IP addresses are Internet Protocol addresses in the form of A.B.C.D, where A, B, C and D are whole numbers between 0 and 255. They can be used with any rule that uses either IP, TCP, UDP or ICMP as the protocol.

IP Address Range

Enter the start and endpoints of the IP address range to filter. All computers in the range will share the filter, so a separate filter is usually recommended for each user rather than using a range. That allows operations such as weighting and prioritization to be performed per user, rather than treating a group of users as a single block.

Any IP addresses are valid for the range as long as the start address is less than the ending address.

MAC Address

Enter the MAC address to filter. MAC addresses are of the form AA-AA-AA-AA-AA-AA, where 'AA' is any hexidecimal value between 00 and FF. Use the Find ... button to convert a known IP address to its MAC address.

Address Group

Select the group of addresses to filter, or click the Find ... button to create a new one.

All Ports

Filter all traffic regardless of port for this endpoint.


Enter a port number of select one from the list.

Port Range

Enter a range of ports to filter.
