Ken,

Thanks for the reply.

Should the showroom PCs then be attached to the WRT switch, or the regular
LAN switches?

The regular LAN switches. If I'm understanding correctly what you're
doing, because you have a separate router between your LAN and the
internet, nothing should be connected to the switch side of the WRT.
The only things on that side of the WRT should be the actual wireless
device.


OK

I also don't see in this situation where you would need multiple IP
addresses on a NIC,


It is because I want the wireless devices (behind the WRT) to be able to
talk to the PCs, but *only* the PCs in the showroom and not the rest of the
LAN, the 520, or the internet.

That led to the original suggestion of having them in a separate mini LAN,
using a second NIC with no bridging between the dual NICs. Given that
configuration, it is easy for me to see how it would work the way I want.

If I fed the WRT WAN port to the regular LAN switches and don't have them
using a different IP address, how do I route the wireless devices to the
desired PCs without them also seeing the other PCs and 520 etc?

For that matter, once the WRT is in a different IP range and subnet, won't
it need a default gateway or route to the LAN to find the desired PCs even
if they are in a different subnet? And once I do that, why can't they see
everything else too?

I have a feeling I'm missing something really fundamental in what you are
suggesting. :(
