IP FILTERING
Figure 32: Router — IP Filtering
Add Custom IP Filters
You can define up to 20 IP filters. Each IP filter is identified by a unique number (from 1 to 20). Click Add to add the
filter to the Custom IP Filters table. Once all filters have been added, click Save & Apply to save all changes.
An IP packet goes through the filtering logic:
1)
An IP packet is received on one of the interfaces and is destined to the Vanguard unit
OR
2)
An IP packet is sent by the Vanguard unit
OR
3)
An IP packet is forwarded by the Vanguard unit.
The filtering logic is the following:
if exists(filter[1]) AND match(packet, filter[1]) then apply(action[1])
else if exists(filter[2]) AND match(packet, filter[2]) then apply(action[2])
else if exists(filter[3]) AND match(packet, filter[3]) then apply(action[3])…
else if exists(filter[20]) AND match(packet, filter[20]) then apply(action[20])
else process packet normally.
Where:
exists(filter[n]) -> The user as defined filter number n.
match(packet, filter[n]) -> The IP packet matches filter number n.
apply(action[n]) -> The action identified in filter number n.
Each criteria has an Any radio-button that matches all values for that criteria.
Each criteria has an Exclude check-box that inverts the sense of the match.
