Is anyone bridging a bunch (20+) vlans onto one bridge0? My goal is to do what the HandBook says I can do: The customers are completely isolated from each other, the full /24 address range can be allocated without subnetting. http://www.freebsd.org/doc/handbook/network-bridging.html#AEN40688 Last time I tried this (8.1) I got a bunch of unicast flooding and it busted my network. I'd like to see a 'nounicast' flag for bridge members... Say, I've never looked into it, but do unicast floods go to a broadcast mac address (eg FF:FF:FF:FF:FF:FF) that I could block via layer2? more on Unicast Flooding: http://packetlife.net/blog/2010/jun/4/blocking-unknown-unicast-flooding/ Rudy
