Connect securely to home/work computers over the Internet. You could be at work, at a
friend’s house or on the road.
Equipment Needed:
1- A solid broadband connection to the Internet at home or work where CWR-854 is
used. CWR-854 needs to be configured for IPSec VPN capability
2- A client system with a VPN client software. We used SSH-Sentinel VPN client
software ( a trial version is available on the Internet)
Configuration Overview:
In the first scenario we will be working with two computers and a CWR-854 VPN router.
The assumption is that we are away from home and need to access a computer on the
home network connected to CWR-854. The computer we’re working from is connected
to the Internet through a Cable/DSL modem or we are dialing up using a modem.
In the second scenario, the client system is also behind a NAT route. In this case the
computer we’re working on is connected to a router and through a Cable/DSL modem to
the Internet.
First Scenario:
To configure VPN both on the client system as well as the router, we need to know about
the IP address schema used on the home network. By default the LAN IP of CWR-854 is
192.168.1.254. Computers that are be accessed from the Internet are better to have a
fixed IP address assigned to them. Below are what we need to know:
Home WAN IP address (this is the WAN IP of the VPN router CWR-854 used at home
or work) for example: 204.30.90.120
Home LAN IP address: (Default LAN IP of CWR-854 is 192.168.1.254)
Home LAN IP Network : (Default is 192.168.1.0, Subnet 255.255.255.0)
Computer to be accessed on the home network: 192.168.1.100
VPN Client (remote) computer on the Internet for example: 204.30.90.200
