Chapter Five: Minimizing ISDN Charges Traffic filtering
64
Traffic filtering
By using the DIVA LAN ISDN Modem’s IP filters, you can selectively drop outgoing traffic to reduce your
communications charges. This can be useful if you have applications on your LAN that regularly send
non-critical traffic across the ISDN link.
For more information on filters, see “IP filters” on page 119.
