No, I had to change the IP address on the R6100. Also I had the R6100 pluged into the R7000 in the yellow port. I had to change this to plug the R7000 into one of the four out ports on the R6100 along side the magic jack works great now. Thanks, Paul.

sounds like a doulble nat caused by one router connected to another router which will cause havoc with port forwarding

you might consider using the r7000 in ap mode
