I've tried to add my devices to a second DHCP server on a different VLAN to create the following situation:
DHCP VLAN 5 (192.168.5.*)
- device1 192.168.5.20
- device2 192.168.5.21
- etc.
DHCP VLAN 15 (192.168.15.*)
- device1 192.168.15.20
- device2 192.168.15.21
- etc.
Adding the second registration isn't possible because of an already existing DHCP static lease.
More inconvenient is that after the VLAN 5 static definitions have been made, no DHCP lease is provided when accessing the VLAN 15 network. In this case, for me it impossible to test the connection on VLAN 15 while having a static lease present on VLAN 5.
I'd like to see this changed in a per DHCP server static lease option per device.
