@da_667 thanks for that! It seems I misspoke in my inexperience and was actually referring the the MAC on the virtual adapter used to connect pfsense WAN interface to the bridged network. I recorded the MAC address after esxi generated it and made the dhcp lease for it, but it doesn’t seem to be working. My dhcp server logs don’t show the MAC in any attempted DORA communication (discover or request). I am considering rebuilding the entire lab from scratch just for the experience haha.
