Virtual private networking 76
A vpn client access allows a remote computer to connect to your network from any location on the internet the remote computer is one tunnel endpoint running the vpn client software the n300 wireless modem router on your network is the other tunnel endpoint see set up a client to gateway vpn configuration on page 80 77
Client to gateway vpn tunnels 77
Client to gateway vpn tunnels provide secure access from a remote computer such as a telecommuter connecting to an office network 77
Figure 1 telecommuter vpn tunnel 77
Figure 2 vpn tunnel between networks 77
Gateway to gateway vpn tunnels 77
Gateway to gateway vpn tunnels provide secure access between networks such as a branch or home office and a main office 77
Overview of vpn configuration 77
Two common scenarios for vpn tunnels are between a remote computer and a network gateway and between two or more network gateways the dgnd3300v2 supports both types the dgnd3300v2 supports up to five concurrent tunnels 77
A vpn between two or more netgear vpn enabled routers is a good way to connect branch or home offices and business partners over the internet vpn tunnels also enable access to network resources across the internet in this case use gateways on each end of the tunnel to form the vpn tunnel end points see set up a gateway to gateway vpn configuration on page 90 for information about how to set up this configuration 78
N300 wireless dual band adsl2 modem router dgnd3300v2 78
Plan a vpn 78
Table 1 vpn tunnel configuration worksheet 78
This set of configuration information defines a security association sa between the two vpn endpoints when planning your vpn you have to make a few choices first 78
To set up a vpn connection you need to configure each endpoint with specific identification and connection information describing the other endpoint you configure the outbound vpn settings on one end to match the inbound vpn settings on other end and vice versa 78
Virtual private networking 78
When you set up a vpn it is helpful to plan the network configuration and record the configuration parameters on a worksheet 78
Will either endpoint use fully qualified domain names fqdns fqdns supplied by dynamic dns providers see use a fully qualified domain name fqdn on page 147 78
Will the local end be any device on the lan a portion of the local network as defined by a subnet or by a range of ip addresses or a single computer 78
Will the remote end be any device on the remote lan a portion of the remote network as defined by a subnet or by a range of ip addresses or a single computer 78

This appendix is a case study on how to configure a secure ipsec vpn tunnel from a netgear dgnd3300v2 to a fvl328 this case study follows the vpn consortium interoperability profile guidelines found at http www vpnc org interopprofiles interop 01 html 144
Step by step configuration 145
A dynamic dns ddns service allows a user whose public ip address is dynamically assigned to be located by a host or domain name it provides a central public database where information such as e mail addresses host names and ip addresses can be stored 147
Configuration profile 147
Many isps provide connectivity to their customers using dynamic instead of static ip addressing this means that a user s ip address does not remain constant over time which presents a challenge for gateways attempting to establish vpn connectivity 147
