MR1100ATT problems with Port Forwarding

Hello NetGear Community. 

I am trying to use my MR1100ATT with a third-party VPN service/VM and cannot seem to get the required IPSec UDP ports open on this router.  I enabled Port Fowarding for both ports and listed the correct machine IP for the forwarding with no luck. When scanning the router, the UDP ports are CLOSED.  My backend configuration is solid. To test this, I switched over to using a new FIOS router...enabled port forwarding to the above mentioned ports/IP and within 15 minutes of swtiching, everything was working fine.  I've narrowed it down to the MR1100 being the problem. 

Anyone have issues with port forwarding or not being able to get IPsec packets through the MR1100?  

Thanks
