Packet Filtering
11.1 Filtering
Compex WP11A+ allows Packet Filtering rules to be defined based on three factors,
Source IP Address, TCP Port and Time. IP Packet Filtering examines the outgoing
packets and decides whether to bypass or to block them. After the Packet Filtering rules
have been defined, the users may select to bypass or to block the outgoing packets that
do not match the rules.

Adding Filtering Configuration
For example, assume that a rule has been defined as "TCP Port 23 (used by TELNET)
from any IP on any day at any time". If the “sent” radio button is selected, all outgoing
packets will be sent except TELNET session. If the discarded radio button is selected,
all outgoing packets will be blocked except TELNET session.
