Obviously some misunderstanding here. I thought you meant there was no
direct station-to-station traffic in *any* circumstances...

Presumably they can if the AP is set as the default route...

But I would like to stick an ADSL-PCI card in as well.
I suppose I can dream :-)....
If I managed to build such a box I could stick all my server software on
it such as mail/web/ftp/dns as well as a proxy server and provide a
gateway to an internal network, ie a box which you can just plug into a
telco socket and provide instant access for a number of users. I'm sure a
proxy server would provide better Internet access than having several
users accessing the Internet individually. You could also build in some
access control. I don't see how you could do it otherwise.
