So does each physical port go to separate wireless bridge/AP? Sounds ideal for VLAN trunking. > What's the preference for multiport cards out there now? I'm not sure. It sounds like many have abandoned such things for GigE cards and trunking. Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
