Description
A free form text field. Give your filter an intuitive name.
Version IPv4 is selected by default. IPV6 can be alternately selected. For the filter to be IPV6 configured and
effective requires the gateway be installed on a network that is either a pure IPV6 network having that protocol
enabled or it is both IPV4 and IPV6 dual protocol enabled/configured. Choosing IPV6 means both the Source and
Destination IP address as described below must be specified in IPV6 format (e.g. the following is an IPV6
compliant, hexadecimal address.
2001:0DB8:AC10:FE01:0000:0000:0000:0001).
[TCP/UDP,TCP, UDP, or ICMP] Sets the protocol profile for the filter you are defining. TCP/UDP is most
commonly used.
Enter the source IP address of a LAN side host for which you wish to filter/block it's outgoing traffic for the
specified protocol(s).
NOTE: The address specified here can be a particular address or a block of IP address on a given network
subnet. This is done through appending the address with the routing “/prefix†l ength decimal value
(preceded with the slash) associated. Use of a valid decimal routing prefix for defining the subnet mask per
CIDR notation is required).
Set the outgoing host port (or range of ports) for the above host (or range of hosts defined by optional routing
"/prefix" s ubnet mask) to define the ports profile for which egress traffic will be filtered from reaching the
specified destination(s).
