I wish I had known the full picture before..
then I could have added the required bits:

So  think you need this:

ONT]----em0]lower---downstream[eapfilter:]nomatch----vlan0[VLAN]downstream----upper[em0... 

                                                          eapout
                                                              |
                                                              |
                                                              |
RG]------em1]lower---------------/

               ie. use an etf node on each interface.

     ngctl mkpeer igb0: etf lower downstream
     ngctl name igb0:lower eapfilter
     ngctl mkpeer igb0: vlan upper downstream
     ngctl name igb0:upper vlanheader
     ngctl msg vlanheader: addfilter '{ vlan=0 hook="vlan0" }'
     ngctl connect vlanheader: eapfilter: vlan0 nomatch
     ngctl connect eapfilter: igb1: eapout lower
ngctl msg waneapfilter: 'setfilter { matchhook="eapout" 
ethertype=0x888e }'

note the vlan node is inserted "backwards"..
