It was porbably v6 only (W)LAN. dhclient(8) in base does only care about IPv4. For IPv6 stateless, you need to watch sysctl(8) net.inet6.ip6.no_radr and ifconfig(8) -no_radr By default, if set ipv6_activate_all_interfaces="YES" in rc.conf(5), I think you should get a stateless IPv6 address (since net.inet6.ip6.no_radr=0, hence no no_radr flag for your IPv6-enablef interface (wlan0)), as long as there's a router in the (W)LAN advertising. For stateful IPv6, you must install somethink like KAME-dhcp6 (ports/net/dhcp6). But the latter isn't widely deployed, most setups I've seen have routers advertising and clients with stateless setup. Can't tell you out of mind what your rc.conf(5) should look like to enable stateless config for distinct interfaces, but I'm sure you'll quickly find if you look for the above mentiond key words. Viel Spass auf'm Filmfest :-) -harry
