Hi Thufir,

Here is another idea.  I don't know if this will work, it seems like
it might, but since you already have a hub, it's at least worth a
shot.  Plug your 802.11b AP into the hub, then the computer (one
ethernet port) and the VOIP device both into the hub.  This might not
work because of the differences between hubs and routers, but it just
might.  And you won't have to setup your computer to run NAT (though,
since you have two NICs, it might be something you want to do later).
Oh, and as far as your last question, a hub is meant to be transparant
(which is one difference from a router) so you shouldn't see it.  It
should be just like talking directly to the VOIP device.  You just
don't need a crossover cable if using a hub.  You might not need a
crossover cable anyway if the device can sense whether it needs to do
crossover or not (as mentioned by someone else above).
