IP-MAC Binding

1 IP-MAC Binding

This module enables you to bind an ip address to a MAC address. Please notice:

• When "ip-mac binding" is enabled, WFilter NGF DHCP server will assign static ip addresses to clients.
• WFilter NGF does not act as a DHCP server when deployed as a network bridge.
• If you have another dhcp server, for "ip-mac binding" to work properly, please modify your DHCP server to assign listed static ip addresses to clients.
• If you want to apply binding to clients connected with a three layer switch, you need to enable "MAC Detector".

2 Settings

• For ubound IPs, you can choose to:
  • "Block All". No internet access for ubound IP addresses.
  • "Allow All". Allow internet access for ubound IP addresses.
  • "Block below IP". Local IP address belongs to the IP ranges will be blocked.
• Static ARP: enable static ARP for listed IP-mac addresses.
• For ubound MAC addresses, you can set each lan subnet to assign IP address or not.
  • "Disable". Do not assign IP to unlisted MAC address.
  • "Enable". Assign IP to unlisted MAC address.
• Please note: because client will cache the assigned ip for a while, sometimes you can not obtain the new bound ip immediately. For example, in windows system, you need to run command "ipconfig /renew" to force dhcp renew.

• Click the "state" icon, you can turn on/off the binding.

Please notice: even a binding is in "off" state, static ip address will still be assigned by WFilter's DHCP.

4 Import & Remove

• Scan and Import: scan local ip & mac list for importing.
  • Without "MAC Detector", only local ARP table will be scanned.
  • With "MAC Detector" enabled, it also can import clients detected by "MAC Detector".

• Import List: import a pre-defined IP & mac list.

• Delete: delete ip-mac list
