A client has a number of firewalls and 2 AD servers, one on prem and one in Azure. They wish to control IP address assignments in Windows instead of on each firewall. This makes sense as using Central to manage a number of firewalls is slow and somewhat cumbersome as one can only manage one firewall at a time.
We setup DHCP scopes on the Windows Server, setup DHCP replication. Setup DHCP Relay to both servers. This is working well for the most part. One site has an issue and I had to configure DHCP back on the FW. In combing through the firewalls, this one has a Bridged LAN interface AND Enable routing on this bridge pair. Most other sites do not have Bridged interfaces, but the ones that do, have the routing option de-selected.
Does anyone know the impact to DHCP when Routing is enabled? I've reviewed a few articles, but nothing definitive could be found.
