[X4U] Attaching A Router To Router

[Juan Pablo]

I have to agree, i would use a switch, i theory you dont have to setup 
anything with it, if they are using DHCP he would have no problem, 
unless the ip assignment is made based on  MAC address, but thats not 
commonly used. I suggest you to tell your friend that he should try 
with a switch, buying a router its s waste of money for this case.
