Re: ip theft!!

[Bill Sangiwa <bsangiwa at twiga.com>]

yes! breezecom breezeaccess devices do that (not breezenet, breezepro from
the same do not support ip and broadcast blocking), Wi-Lan Hopper-plus, do
support, know Lucent also do, point is look for made for ISP, which are
slightly more expensive than the corporate world devices. advantage are
obvious as bandwidth throttling, ip address controls, broadcast filter (as
u may allow/disallow PPPoE, ARP, DHCP, and the infamous Microsoft
Broadcast packets), radius accounting (if you're charging per volume, this
is interesting to look at).. etc!
