5.7.3 Advanced Settings- IP Filter
IP Filtering provides certain Internet firewall protection. The user can enter up to 20 IP filters. Each
IP filter is identified by a unique number (from 1 to 20). When IP filtering is enabled, any custom IP
filters entered by the user as well as predefined IP filters will be taken into account when processing
IP packets. See Figure 29.
An IP packet passes through the filtering logic when IP filtering is enabled:
1) An IP packet is received on one of the interface and is destined to the Vanguard 3G unit
OR
2) An IP packet is sent by the Vanguard 3G unit
OR
3) An IP packet is forwarded by the Vanguard 3G unit.
5.7.3.1 Predefined IP Filters
Block Remote Pings: If IP filtering is enabled, any ICMP echo request coming from the WAN
interface will not be replied to. This prevents remote hosts from detecting your IP address on the
WAN.
Block Remote IP Fragments: If IP filtering is enabled, any fragmented IP packets coming from
the WAN interface will be dropped.
5.7.3.2 Add Custom IP Filters
Fill in the parameters described below and click “Add…”. Your entry should appear in the Custom
IP Filters table on the bottom of the page.
Note: Criteria are for inclusion by default. Select “exclude” if you criterion is for exclusion.
