Dhcp Relay IPSEC

[ab2l]

Hello,

I have a pfsense box with wan PPPOE and I try to do DHCP Relay over IPSEC.

When I enable the dhcp relay, i see in services that it does not start.
After check in logs I see this line :
dhcrelay: Unsupported device type 53 for "pppoe0"

Why ?
How can I say dhcprelay do not use pppoe ?

Thanks
Sebastien
