If I capture on IFACE directly, I'd expect to get all traffic, including the tagged frames (with the tag intact). Looking to be able to bridge/capture/etc. and specifically only receive the untagged frames that haven't already been pulled out into a vlan specific interface. Is there any way to accomplish this without using ebtables or other similar hacks? -- Nathan ------------------------------------------------------------ Nathan Neulinger nneul@neulinger.org Neulinger Consulting (573) 612-1412
