This article explains how to configure IP and MAC binding on RV32x VPN Router Series.
IP and MAC Address binding is a process which links an IP Address to a MAC Address and vice versa. It helps to prevent IP spoofing and enhances network security as it does not allow a user to change IP addresses of devices. The source host IP address and MAC address of the traffic need to always match to be allowed access to the network. If the IP and MAC addresses do not match, the traffic is dropped.

Step 1. Log in to the web configuration utility and choose DHCP > IP & MAC Binding. The IP & MAC Binding page opens:
You can add a bound entry through Discovery or Manual Configuration. If you do not know the IP address and the MAC address of the device, you can discover them, and then you can add those entries in the IP & MAC Binding Table to bind the IP and MAC addresses. If you know the IP address and its corresponding MAC address, you can easily add those manually in the IP & MAC Binding Table which saves the time needed to discover the IP and MAC.
Step 1. Click Show Unknown MAC Address to list out the IP and MAC addresses of the devices which are connected to the router but not yet added to the IP & MAC Binding Table.
Step 2. (Optional) To refresh the IP & MAC Binding Table click Refresh.
Step 3. Check the check box beside the specific IP address that you want to add to the IP & MAC Binding Table. Enter a user name for the device in the Name field for which you want to add the IP and MAC to the IP & MAC Binding Table. The device name helps to easily identify the device instead of by its IP address and MAC address. Click Save.
Step 4. Click OK if you want to save the entry on the IP & MAC Binding Table. It may take some time. Do not re-log in or refresh the page until the entry adds on the IP & MAC Binding Table.
Step 5. The entry appears on the IP & MAC Binding Table:
Step 1. Click Add to add a known IP and MAC address to the IP & MAC Binding Table.
A new row is added:
Step 2. Fill out the following fields.
Step 1. Check the check box beside the appropriate IP address in the IP & MAC Binding Table to select the bound entry for which you want to change information.
Step 2. Click Edit.
Step 3. Change the appropriate information and click Save to save the settings.
Step 1. Check the check box beside the appropriate IP address of the IP & MAC Binding Table to select the bound entry which you want to delete.
Step 2. Click Delete to delete the entry.
Step 1. (Optional) To block devices whose IP address and MAC does not match with IP & MAC Binding Table, check Block MAC address on the list with wrong IP address. This makes it difficult for the user to change the IP address of the devices.
Step 2. (Optional) To block unknown devices which are not included in the list check Block MAC address not on the list. This helps to provide more security in your network.
Step 3. Click Save to save the settings.
