Multi Service Border Gateway User Manual for NexusWay 800 Series
4-1-13 IP-MAC Locking
This function is often used in dormitory network where Internet connection is limited.
When Default Deny is selected, all the connections are denied by default except the ones
whose IP-MAC combinations have been setup with this option.
When Default Allow is selected, enter an IP and MAC address pair to lock together. If a user
tries to connect using that IP from another MAC address, or uses that MAC address but a
different IP, the connection will be denied. Connections will be allowed if both of the IP and
MAC address match a single entry or neither match a single entry. Every connection matching
exactly one condition of one rule will be dropped. You can also enter a * in the IP field and
enter a MAC address. This will deny all connections using any IP from this MAC address. Any
machines not matching any entries on the list will be allowed by default.
Please note that if you do not set the
IP Address
and
MAC Address
, these 2 options will be
invalid.
NOTE

Click Add to add the setting into the IP-MAC Locking List, or click Reset to clear
the settings and enter them again.
