5.6.3Filtering Setting

Compex SGX3226 allows Packet Filtering rules 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.

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 “forwarded” radio button is selected, all outgoing packets will be sent except TELNET session. If the blocked radio button is selected, all outgoing packets will be blocked except TELNET session.

Click on Filtering section at the Configuration window and the GUI will appear as shown:
