I've always thought of it as the route of from one IP address to another
if a direct connection cannot be established.

Surely the AP can ping .1 and .2 so why wouldn't tracerte find a way from
.1 to .2 via the AP using the defaullt route?

This is where my knowledge gets a little hazy. I thought a NIC defined
the hardware and the bridging was done using software...

There are quite a few ADSL PCI cards around and many have Linux drivers so
maybe it would be possible to port them to OS/2, although I have no idea
about how.

Thanks. I'll have to try out one of these Linux apps some day.

Yes, I don't like the idea of having to load a whole range of software on
every client including firewall software when everything could just be
installed on the gateway. Also a proxy provides quite a few options for
access control for specific machines as well as being able to block
'undesriable' web sites for the whole LAN.
