Re: PIX log message

the log suggested that a broadcast for netbios-sn has been received by the pix. and by default, pix will drop any broadcast packet.

i guess it cannot be avoided, as this broadcast is generated by all windows-based host. it is used to map the computer name to the ip address, e.g. you can use a computer name to share a file etc.
