 When using pppoe a separate device is created that can be used to filter against.  When using IPoE with dhcp same device reference is shared by the IPoE WAN link and the modem LAN web page link.  My modem is setup at 192.168.5.1. The fire wall needs to be modified to consider this shared device instead of separate one. Other than changing the $wan reference from ppp1 to eno1 the postrouting to the modem needs to be made IP range specific. ++++ e.g.| When using pppoe a separate device is created that can be used to filter against.  When using IPoE with dhcp same device reference is shared by the IPoE WAN link and the modem LAN web page link.  My modem is setup at 192.168.5.1.
