Re: (Retry) Bridging a wi-device with a LAN-adapter

Depending on your situation this setup will work fine:
{internet} -- [fxp0 <Box> wi0 (AP)] -- ( ~~  ) -- Laptop

While this will not, because the second (clinet) box cannot be bridged.
{internet} -- [fxp0 <Box> wi0 (AP)] -- ( ~~  ) -- [wi0 (Infra) <Box>
fxp0] -- {internal network}

Thanks,
Tony Toole
