I'm not an EdgeOS expert. I tried DHCP with multiple subnets on a normally
statically configured network during the MF worm fun in May. The GUI was worse
than useless. The CLI was almost as bad because it sorted the networks while
building the isc-dhcp config file. ISC-DHCPd seems to need the first shared
network to be the primary network defined on the interface at the OS level. I
don't remember if the rest had to be defined in order.
I wrote the ISC-DHCPd config myself and forced it into the right place. That
worked for recovery of the defaulted airOS devices, but I wouldn't try yo use
it in production. It was a lot easier to put a MikroTik on the same layer 2
network as DHCP server only. Unfortunately, I only had one MikroTik with me
and needed servers.
That EdgeOS problem cost me most of a day. Mostly because I couldn't believe
such a basic feature was so completely broken. I thought it was me and the
lack of sleep.
