I have FIOS service with the Verizon-supplied Westell 9100EM as my primary router. I currently have a Cisco RV180W connected to a LAN port in the Westell. All of my home computers and other ethernet devices connect to the Cisco router. Equipment connected to either LAN / subnet has full internet access. I am trying to use Cisco's QuickVPN client to establish a VPN connection from remote locations to my home LAN (via the VPN functionality on the Cisco router). I cannot get this to work and Cisco tells me it is because QuickVPN will never work if the Cisco router's WAN interface has a non-routable IP address (ie, is double NAT'ed). That is indeed the situation for me. So I am trying to figure out what options I have to try and make this work. The two things I think may be worth trying: bridging or putting the Cisco router into the Westell's DMZ. Does anyone have experience with similar issue / resolution, using one of these approaches (and guidance regarding the steps to make it work)? Or any other ideas?
Thanks,
Adam
