Guide: How to Setup DHCP Server on OPNsense

[beki]

Dear Beloved Zenarmor Community,

The Dynamic Host Configuration Protocol (DHCP) is a critical network administration protocol that facilitates the automatic assignment of IP addresses and other network configuration parameters to devices within a network. In current networking, the number of connected devices is expanding at a rapid pace, and DHCP is essential for facilitating network administration.

OPNsense firewall offers DHCP service for IPv4 and IPv6 clients, referred to as ISC DHCPv4 and ISC DHCPv6, respectively. By default, OPNsense employs the extensively used ISC DHCP server. However, as of version 24.1, KEA is now available as an alternative due to the ISC DHCP's end-of-life. The long-term ISC will be removed from OPNsense in the future.

In this guide, we explain how you can set up ISC DHCP and KEA DHCP servers on the OPNsense firewall.

Best Regards,

Zenarmor Team

1st impression of Kea has been half baked at best and I am not quite sure if it's ready for "Prime Time!" 
If you look at ISC vs Kea. ISC is by far more reliable then Kea. I think that if ISC is dropped. I am lucky enough to have a switch and a Pihole that can provide that until at some point very far into the future.
