I would suggest that you either use per-VLAN IP networks, or make a bridge of all VLAN interfaces on the Linux system and use iptables to control intra-VLAN-traffic. Something like setup 1b perhaps: http://marc.theaimsgroup.com/?m=105098558615614 To run dhcpd successfully (if you want to) you'll also need to do vconfig set_flag eth1.2 1 1 for each VLAN interface included in the bridge. //Peter
