DHCP on Guest Networks 2 and 3

[andrewk123]

Is your feature request related to a problem? Please describe.
I use an XT8 Router with 2 x XT8 nodes. I use an external DNS and DHCP server (PiHole) attached to a LAN port on the XT8 Router. For this configuration to work, I have the IP address of my PiHole set as the DNS Server IP Address and the internal DHCP server disabled. Everything works correctly with the exception that I cannot use Guest Networks 2 and 3 since devices on those networks cannot access the DHCP server (PiHole) attached to a LAN port on the XT8 router. If I configure the IP address/DNS of the device connected to the Guest Network manually then everything works but this does not meet my use case.

Describe the solution you'd like
What I would like to request is that an option be added to the Guest network configuration to allow devices on guest networks 2 and 3 to broadcast DHCP requests to and receive responses from the LAN allowing the PiHole DHCP server to provide IP addresses to devices on Guest Networks 2 and 3. I'm suggesting this as a configurable option since some users may prefer the current operation.

Describe alternatives you've considered
An alternative approach would be to add an option for guest networks 2 and 3 to offer DHCP services (as is currently offered on Guest Network 1).

Additional context
