6.4.2 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. 52) performs a similar function.
Outgoing IP Filter
The default setting for Outgoing traffic is
ACCEPTED . Under this condition, all
outgoing IP packets that match the filter rules will be BLOCKED .
To add a filtering rule, click the
Add button. The following screen will display.
Filter Name

Protocol TCP, TCP/UDP, UDP or ICMP.
Source IP address Enter source IP address.
