Also, ng_vlan's "downstream" hook should be connected to ng_ether node corresponding "real" interface like em0 and its hook "lower". Then real interface passes incoming packets to ng_vlan instead of normal delivery. ng_vlan strips incorrect vlan tag and result is delivered normally as recei= ved from ngeth0. Ethernet frames received without vlan tag will be dropped by this comple sc= hema but it is possible to process them too by inserting ng_tee node into the gr= aph. ng_tee is capable of combining two streams of data into single one and pass= ing it to arbitrary next node. --=20 You are receiving this mail because: You are the assignee for the bug.=
