@youzersef What if your router providing next server is pfsense.
What needs to be changed in pfsense?   My current settings are that of fog.
Pfsense : 10.22.24.1 : (controls DHCP, next server, etc)
Fog           10.22.24.5 : (Working flawless)
iVentoy                        :  10.22.24.13
Everything I try is sending client back to pfsense, and then errors because it’s getting the boot file for fog, when it’s expecting iventoy_loader_16000
Thanks !  Time to get this project wrapped up 🙂
