Overview of VPN Configuration
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.
Client-to-Gateway VPN Tunnels
Client-to-gateway VPN tunnels provide secure access from a remote computer, such as a
telecommuter connecting to an office network.

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.

- 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

- 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
