I have a properly installed and configured isc-dhcp-server & bind9 box that is correctly updating DNS records based on leases. This works well.
I understand how the isc-dhcp-server can be configured for multi-nic / multi-homed use cases, multiple subnet, etc. What I'm having difficulty with is the proper / recommended configuration for a known client node with reservations. Specifically, I have a laptop with an internal wireless nic as well as an ethernet connection. This laptop (
aio) is configured properly so that when a tethered connection is detected the wifi is disabled to favor the eth0 connection.
What I am trying to accomplish is to have
aiodynamically register this change in bind9 and pull a reserved IP during this switchover. I can't seem to make that happen gracefully as my attempts to configure 2 reservations with the same hostname albeit different macs in isc-dhcp-server fail.
So slightly restated, I'm trying for
Host: aio eth0: 192.168.1.1 uniqueMac1 wl0: 192.168.1.2 uniqueMac2
Any help or direction appreciated.
