@SteveITS: Good one, Steve.
Sigh. But, computerA will probably be a Netgate 1100 and computerB will be an embedded device with an older Linux kernel on it, perhaps 2.6 or 4.4.
Thanks.

@Joe0x7F If I do that with two Debian clients the second one get's an IP from the DHCP range.
What DHCP server are you using, ISC DHCP or KEA?

@patient0: KEA

I would like to setup Static DHCP Mappings (with static ARP entries)
Are you sure you want static ARP entries rather than just DHCP Mappings.
In my experience that causes cryptic failures. See https://forum.netgate.com/post/1216320The alternative is just set the DHCP Mappings and let pfsense determine the ARP entries.

Thanks!

@Joe0x7F oh, I just see you wrote about static ARP entries. Ignore my reply, I did static DHCP mapping.
