Manually Assigning IP Addresses to Remote Users

To simply the process of connecting remote VPN clients to the DGFV338, the ModeConfig

module can be used to assign IP addresses to remote users, including a network access IP address,

subnet mask, and name server addresses from the router. Remote users are given IP addresses

available in secured network space so that remote users appear as seamless extensions of the

network.

In the following example, we configured the ProSafe DGFV338 using ModeConfig, and then

configured a PC running ProSafe VPN Client software using these IP addresses.

• NETGEAR ProSafe Wireless ADSL Modem VPN Firewall Router

– WAN IP address: 172.21.4.1

– LAN IP address/subnet: 192.168.2.1/25 5.255.255.0

• NETGEAR ProSafe VPN Client software IP addres s: 192.168.1.2

After IKE Phase 1 is complete, the VPN connection initiator (remote user/client) asks for IP

configuration parameters such as IP address, subnet mask and name server addresses. The Mode

Config module will allocate an IP address from the configured IP address pool and will activate a

temporary IPSec policy using the template security proposal information configured in the Mode

Config record.

Note: Selection of the Authentication Protocol, usually PAP or CHAP, is configured

on the individual IKE policy screens.

Note: After configuring a Mode Config record, you must go to the IKE Policies menu

and configure an IKE policy using the newly-created Mode Config record as the

Remote Host Configuration Record. The VPN Policies menu does not need to be

edited.
