--000e0cdfd620621a5304ba7767f4 Content-Type: text/plain; charset=ISO-8859-1 I've tried netgraph nodes too! but stuck on the next step and asked the problem on this forum and received no answer:( my netgraph scenario is described below: I have designed a topology(attached) using netgraph to add vlan2 tag to the frames coming from eth0(vlan port) and send it to eth1(trunk port) to go out of the box. it works fine. Then I tried to add another interface like eth0 which named eth2(vlan port) to be tagged vlan2 too. After that, I bridged eth0 and eth2 using ifconfig(as vlan ports are connected to each other on same vlan id). When traffic comes from eth0(system1) to the destination eth2(system2), all traffic also sent out eth1 which is not suitable! In the mentioned scenario, I don't want the traffic pass to the eth1. Is there any way that eth1 recognize which mac addresses don't belong to this box then sends the traffic out? I mean I want to send taraffic out of eth1 when the destination is not accessible via FreeBSD box so it should be sent out to be find out.
