long story short:
pihole dhcp on bullseye does not seem to be working for network devices.
my main pihole (dns + dhcp) seems to have died on me, however i have semi recent backups of most of the files; iptables, network, and pihole. i have a spare pi that i upgraded to bullseye, and using the backup files mostly have a running pihole again. when i access the pihle gui/settings, seems to have the necessary configs, and the static leases, and the "dhcp server enabled" checked. however, devices do not seem to be able to get any leases. iptables should be configured exactly to how the main server was, allowing dhcp 67/68. dns is working fine for devices, when pointed to this pihole (and manual static network settings)
Thanks, resolved. did not realize it reads ALL files in the "/etc/dnsmasq.d/" folder; which contained a backup from another system which indeed includes the no-dhcp. sorry, and thanks!
