I think that all of you are making a very good point, and watching some of the demonstration videos online is very convincing. I've ordered the 2nd NIC and will set up the CORE as recommended. I am still a little confused, though. The core will be acting as DHCP server, not my router, as it is now? Will I need to disable the the DHCP server functionality on the router then?
Thanks again,
Lev
