Installing new nic in pfsense


So I need some help before purchasing a new NIC for our PFSENSE. Right now our PFSENSE has 2 ports. 1 for LAN and 1 for WAN. Our company provided us a new WAN so we are thinking to make PFSENSE Dual WAN with Failover.

My concern is, we will be taking out the old NIC and install a new one with additional ports. Will there be a problem with our existing configuration if we do this?

We cannot add another NIC since there is no available port for the NIC card, that is why we are thinking of swapping the NIC for a new one.

Hoping for your little help. Thank you.

You can manually change out NIC from the console when you change out the card.
