6.4.1
IP Filtering
This screen sets filter rules that limit IP traffic (Outgoing/Incoming). Multiple filter
rules can be set and each applies at least one limiting condition. For individual IP
packets to pass the filter all conditions must be fulfilled.
NOTE:
This function is not available when in bridge mode. Instead of IP
Filtering,
MAC Filtering
(pg. 46) performs a similar function.
OUTGOING IP FILTER
By default, all outgoing IP traffic is allowed, but IP traffic can be blocked with filters.
