A few things..

1/ thisn is a FreeBSD list so we are not very familiar with linux.
2/ PPPOE uses PPP which is a point-to-point protocol and does not support
broadcast.
3/ DHCP is a broadcast protocol and does not support point-to-point
networks.
4/ PPP (oE) has its own IP allocation mechanism.

But note that he is using DHCP relaying to a remote DHCP server. This
original DHCP broadcast is picked up and turned into a unicast message for
relaying to the DHCP server. This works quite happily over PPP or indeed any
intervening IP network and any number of hops.
