Need Netgraph Help [fixed]

[John Lyon]

That's interesting.  Why did you insert ng_vlan "backwards".  My though is
that you would want to do something like this (because the whole point is
you want to remove the VID=0 tag since FreeBSD won't bind to VID=0):

ONT]----em0]lower---downstream_vlan0[VLAN]------downstream
[eapfilter:]nomatch--------upper[em0...

                             eapout

                                 |

                                 |

                                 |
