5.4.3 DHCP Auto Binding
If the hosts change frequently on your LAN, it is very troublesome to configure DHCP
manual bindings. Using ARP Spoofing Defense feature also needs periodic maintenance.
So usually there are some users who can’t access the Device and Internet. To deal with
these issues, the Device provides DHCP auto binding feature.
Once the DHCP auto binding is enabled, the Device will immediately scan the LAN to
detect active hosts connected to the Device, learn dynamic ARP information and bind the
related valid IP and MAC address pairs. After that, when a client host obtains an IP
address from the Device that acts as a DHCP server, the Device will immediately bind this
host’s IP and MAC address pair. So it can effectively protect the Device and LAN hosts
against ARP Spoofing.
Figure 5-20 DHCP Auto Binding
Enable DHCP Auto Binding: It allows you to enable or disable DHCP auto binding. If
you select this check box to enable DHCP auto binding, once a LAN host obtains an
IP address from the Device that acts as a DHCP server, the Device will immediately
bind this host’s IP and MAC address pair. Else, the Device will not perform auto
