Cannot remote desktop out with Westell 9100

I cannot remote desktop to my in-laws' PC in China after installing FIOS westell 9100. Before this, I have a cable modem and I can remote desktop to a PC in China without problem.

Also before I was using a NetGear router and did not have this problem. I have to think this is a problem with the Westell 9100 router.

Any help would be most appreciative.

Thanks in advance
