Is it possible to run both dhcp and PPPoE over the same Ethernet port. I want to set up a pool of ip address for PPPoe and one pool for dhcp, so some routers out in field will be dhcp and others will PPPoE.
In Client mode is possible.
In Server mode, i never tested. But can be possible too.
You can try test and see the results.
Yes you Can
But in my opinion it is better to use VLAN to seperate The Traffic
