Reserving IPs Spills to other Interfaces.
-
I just noticed something unexpected (to me) when reserving an IP in DHCP on a VLAN. My client computer has the usual wired and wifi interfaces. I’ve entered the wired MAC address into the Static DHCP Mapping reservation form, and as expected when I interrogate the wired interface it reports the IP that I reserved. The unexpected thing is when I interrogate the wifi interface it also reports the same IP that I reserved for the wired interface. As I did not make any explicit reservation for the wifi MAC address I expected to see a dynamically allocated IP address within the DHCP range for the wifi interface. Is this the intended behaviour when reserving an IP in the Static DHCP Mapping process?

No that's not the expected behaviour as long as the Ethernet and Wifi interfaces have different MACs How are you checking the IP address? What type of client is this happening on?
This seems similar to this thread: https://forum.netgate.com/topic/168763/arp-table-and-internet-issue

How exactly are you doing this?
when I interrogate the wifi interface it also reports the same IP that I reserved for the wired interface
Are you doing a ipconfig /all on the device or a ifconfig if linux?
Your wifi and ethernet ports would have different macs.
Please show us what your seeing, the arp table from pfsense would be most helpful.. And you calling out what IP your getting. And your saying its the same in both your wired and wireless vlans?

Obviously there is a bridge somewhere.
Most probably the wifi ap is by mistake connected to the wired lan segment.
