> dropping unwanted pkt: no matching service name

try adding
     -S TvNetWork
to your command line.

it looks like in pppoe.c the block

	if((s =3D findtag(pkt, TagSrvName, &len, 0)) =3D=3D nil)
		return bad("no matching service name");
	if(len !=3D strlen(srvname) || memcmp(s, srvname, len) !=3D 0)
		return bad("no matching service name");

should be inside a if(srvname[0] !=3D '\0') { ... }.
