Why are there two ethernet cards on A and C but only one on B?
If B is the portal to the internet, how does it connect to the router?  
Doesn't it use an ethernet card for that?  If so, how does it connect to 
Remote C?  That would also need an ethernet card 

How does Remote A connect to the internet, does it route through Remote C to 
Remote B or is it not supposed to?

And how are those cards setup?  Internal & external subnets to what?
