On the bottom of this screen, at the
Item Number (0 to Add, # to Edit, ±# to Delete) prompt:

IP Filters (IP Filter Configuration screen) | |

Allows you to build multiple rules for an IP filter. A filter consists of a set of rules applied to a specific interface to indicate whether a packet received or sent out of that interface is forwarded or discarded. You can add, edit, or delete filter rules within a named set.
A filter works by successively applying the rules to the information obtained from the packet header until a match is found. The filter then performs the action specified by the rule on that packet, which forwards or discards the packet. If all the rules are searched and no match is found, the configured default filter action is executed.
Host rules have higher precedence than network rules. Rules apply to the source/destination IP address, source/destination port number, and traffic types, such as TCP/UDP/ICMP. TCP/UDP/ICMP traffic is forwarded or discarded based on the conditions specified in the rule, including source and/or destination address and source and/or destination port number. You can have up to 33 rules per filter. Each rule reduces the packet throughput of the DSL card.
There can be 8 filters per DSL card with a maximum of two filters per DSL port, one inbound filter and one outbound filter. The same filter can be applied as an inbound filter and an outbound filter. Filters are configured on the port card and the processing takes place on the endpoint.
NOTE: Once your rules have been configured, you can then bind and activate the filter on the DSL interface using the Configuration → Interfaces → General screen
