Question DHCP : 1 IPAdress for 2 different MAC?

[ZythumNewton]

Hi!
I had a WIFI cam connected to my network. Depending if it's use my wifi from my main router or via access point, for the same device, the MAC address changer. I can not set fix IP address into my WIFICam (not supported). I need a fix IP adress for my CCTV Software (motioneye).

Ex:
when connected with my router, the MAC address is : 02:0f:b5:22:a5:0f
when connected with my AP the MAC address is : 02:09:b5:22:a5:0f

I use Synology DiskStation for DHCP server, (running linux) and I can't figure out how to fix it.

I try to edit the "dhcpd-eth0-static.conf" my adding two line below:
dhcp-host=02:0f:b5:22:a5:0f,CamBack,192.168.1.22,86400
dhcp-host=02:09:b5:22:a5:0f,CamBack,192.168.1.22,86400
but DHCP won't work.

Can I use a second IP address and make an alias?
Can I modify the "dhcpd-eth0-static.conf" for IP forward?

Thank you in advance
Zythum

Your DHCP entries shouldn't have the port number (86400) in the entry.

86400 is for lease time
--dhcp-host=[<hwaddr>][,id:<client_id>|*][,set:<tag>][tag:<tag>][,<ipaddr>][,<hostname>][,<lease_time>][,ignore]

It's right?

Thank

I solve it!
After reading carefully the documentation, I understand I can use wildcard bytes on MAC address
dhcp-host=02:*:b5:22:a5:0f,CamBack,192.168.1.22,86400
