Title: Can't Access Static IP dnsmasq Hosts reservations
Post by: ButlerofThanos on September 14, 2025, 03:25:34 AM
I recently reinstalled OPNsense and am getting a new introduction to how dnsmasq works.

So far I'm having problems trying to create staticly assigned IPs.

After my initial install, dnsmasq was assigning DHCP IPs just fine (on range 10.10.1.41 thru 10.10.1.245) without issue.

I wanted to create static IP assignments for servers and devices on my network that are permanent for the most part (network printer, NAS, etc...)

I at first created a second DHCP range (10.10.0.41 thru 10.10.0.245) created Host assignments based on MAC address, and set the host name, domain (home.arpa), checked ignore DHCP, hit apply. But the devices weren't accessible at these static IPs, and they were still getting renewed DHCP assignments on the 10.10.1.X DHCP range. Even after a full restart of all devices.

I then deleted the secondary DHCP range and assigned hosts, and widened the original DHCP range to 10.10.0.10 thru 10.10.1.245, and recreated the host reservations with static IPs, made sure FDQN was checked, but the devices weren't accessible (on http or https.)

How do I create static IP assignments that are accessible on a web browser?

Am I missing some a firewall rule?
