Tcpdump filter rules fail
i've some problems using tcpdump with filter rules (running backfire on a wrt54g).
I put the wireless interface (wl0) to monitor mode (wl monitor 1, after that i see a additional interface prism0)
and then i'm able to capture wireless traffic with prism headers.
When i use filter options (like net 192.168.1.0/24) i receive no pakets on the prism interface.
But when i use the filters on the wl0 interface they work (but of course without prism headers).
i'm really confused about that ... any ideas or hints ?
