Perhaps there are other methods, but I have only ever seen this work if the Netgear/VPN router is placed in the DMZ zone.

Hello!<br />
<br />
Got a simple question regarding setting VPN tunnels between two FVS318s Netgear VPN firewall routers.<br />
<br />
I will be setting up two FVS318 routers via a VPN tunnel to one another. &nbsp;I have done it numerous times successfully, providing both FVS318s have a public IP address and all (DMZ) ports available to it. &nbsp; <br />
<br />
In this case, one of the FVS318s will be behind another NAT 3rd party router (router B) issuing it an internal (192.X.X.X) address. &nbsp;<br />
<br />
I just need to know which port(s) must be forwarded on router B in order for the two FVS318's to communicate. &nbsp; I have done this before in the past, and I am sure its 1 TCP port (maybe TCP 1723?). &nbsp;Can anyone confirm?<br />

Setting up FVS318 to FVS318 VPN tunnel behind another router

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

Internet Protocol Security

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
