Connecting 2 sets of MK63

Thank you Michael, 

In fact, I don't need nor wish to connect 2 routers (that in fact would be more simple for me, as you said, I can build a bridge and configure a NAT, have done that many times).

I have bundle 1, router + 2 satellites, running and all is good. What I try to do it take from the bundle 2 only 1 satellite and link it to the router which is already of bundle 1. 

I hope I expressed myself better. 

Thank you
