have you checked _all_ the tables? I was bitten once by rules in the raw table (iptables -t raw -L -nv). Better yet, iptables -t raw -F. > > Has anyone seen this problem before? What is the cause? Seen similar problems when a bridge is used in purely client mode. Bridges can _only_ be used on APs, either plain vanilla APs or AP with WDS. Do not try to bridge a client radio, this mode is not supported by any standard, and it usually won't work. You'll have to do WDS. > > [*] ff02::1 all hosts on a link multicast group. > -- > Było mi bardzo miło. Czwarta pospolita klęska, [...] >>Łukasz< Już nie katolicka lecz złodziejska.
