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...

Really?

Check this:-

Here is something I would like to do using OS/2:-

http://www-106.ibm.com/developerworks/linux/library/l-wap.html


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.
