Trying to figure out a Network Extender Problem

So I am not at a loss for trying to figure out what's the issue with my NE that I just got since I've had VZW service issues in my home for months.




Cable Modem->NAT Server -> Switch -> Network Extender


I've never had any IPsec issues using VPN on any of my work laptops with either Array or Cisco VPN. I went into the NAT server and port forwarding 53,500,4500,52428 on both UDP and TCP. I've tested that it works to another laptop behind the NAT box using both bit torrent tests / windows RDP. So the forwarding should work. I know there is no front end to the NE (which is frustrating) since I am seeing traffic come out the NAT to VZW (and VZW has shown me the local IP). So any advice here? If I plug the NE directly into the Cable Modem, works great in about 5 minutes. I find it hard to believe that this thing won't work with a switch (as per Samsung).


Any other advice here? I might have to add a 3rd NIC to my NAT Server just to dedicate to the NE if I can get the above to work.


Thanks for the help!
