Larry & BBates,Thank you for the quick response on such a tragic day. I guess I should clarify the situation furter and rephrase my question(s):
My reason for doing this is to enable my laptop to connect to our office network for file and internet sharing.
The problem is that the main hub is so far away from my workstation, >200-250 ft. or so, that our cost to install a second cable to allow me to connect my laptop to the network hub directly is prohibitive. Basically, I am trying to allow 2 PCs to share the single cable that connects the hub to my work area. To do this, I thought I'd try to "split" the connection from the existing cable by plugging it into the Barricade's WAN port, and then connecting my desktop and laptop to the standard ports in front.
1) Can the Barricade's WAN port be used as an uplink port?
2) If not, would a crossover cable do the trick?
3) If a crossover cable is the answer, would I be able to use an RJ-45 coupler on one end of the 200 ft.+ straight-through and a short length of crossover on the other to achieve the crossover effect? Remember, I am trying to avoid the hassle & expense of purchasing, crimping, and laying another cable. 
Thanks in advance!
