Before you can use your new network card, you must assign the interfaces in pfsense firewall. The first thing you need to know before assigning interfaces in pfsense is the MAC address of the network card you want to add.
The MAC (Media Access Control) address is a unique set of characters that identifies a network interface card and facilitates communication at the physical layer. It is made up of six groups of characters and the first three groups of characters represent the manufacturer of the network card.
This post provides the necessary steps to assign interfaces in the pfsense firewall.
How to setup interface in pfsense
Go to interfaces, then click on assignments.
Now, identify the MAC address of the network interface card (NIC) you want to assign in pfsense.
If you have more than one network card available, you will see them in the drop-down menu next to Available networks ports.
Select the Mac address you want to use, then click Add.
Click on the network interface card (NIC) that you want to activate and configure.
Check the box enable interface
In the description, give the interface a name. For example: LAN, DMZ, WLAN, WIFI or other.
For your network card to work, you must tell the system how it will find the IP address (Internet Protocol address). In both IPv4 configuration type and IPv6 configuration type, you have several choices, but if you have DHCP service enabled, this is the way to go as it has many benefits and does not require any configuration.
In the IPv4 Configuration Type select DHCP and In the IPv6 Configuration Type select DHCP6.
These are the essential steps you need to add, activate, and configure a network card in pfsense.
When you are done, click Save.
Click on apply changes.
