How do I configure a VPN for Lynksys VPN Router BEFVP41

I want to buy a Linksys VPN/Router BEFVP41 for my work server to replace the current basic router. The reason I want to do this is that I want to connect to this server (Win 2003 Server) from my home computer (Win XP).

I don't understand some of the instructions provided by the lynksys BEFVP41, which I downloaded, to setup the VPN. Please comment the problematic steps (8,9, and 11) below to explain them for me. It would be appreciated.

1. Open your web browser, and enter in the Address field. Press the Enter key. [no problem]
2. When the User name and Password field appears, skip the user name and enter the default password admin. [no problem - yes, I will change the password and username]
Press the Enter key. [no problem]
3. Select the Security tab. [no problem]
4. From the Security tab, select the VPN screen. [no problem]
5. From the VPN screen, select Enable beside VPN Tunnel. [no problem]
6. Enter a Tunnel Name. This name should be unique for this particular tunnel. [no problem]
7. Select Subnet from the pull-down menu beside Local Secure Group. Then, enter the IP Address and Subnet  Mask for this group. This would be your local network's IP Address scheme. [no problem]

8. Select IP Addr. from the pull-down menu beside Remote Secure Group. Then, enter the IP Address and
Subnet Mask for this group. This would be the IP Address scheme for the remote network, the network on the other side of the tunnel.

[Ok, I don't understand this part. Is it asking me to obtain the IP address and the subnet from my Home network, meaning my internet connection?? How do I get around my own home linksys firewall? I don't get it.]

9. Select IP Addr. from the pull-down menu beside Remote Security Gateway. This would be the remote
endpoint's IP Address as seen from the Internet. Enter this IP Address here.

[How do I get this IP? my home computer is protected by a home firewall (linksys router/firewall).]

10. Select a type of Encryption and Authentication for the tunnel your are establishing, making sure that both sides are identical.  [no problem]

11. Check PFS (Perfect Forward Secrecy) and enter the Pre-Shared Key and Key Lifetime.  [Need some explanations, Where do I get these things?]

12. Click the Save Settings button. [no problem]
To test your connection, click the Connect button. [no problem]
Your tunnel should now be established.

You need a pair of routers to get a VPN up.

8 is the subnet of your home network, optained via


9 is the public IP of your Home router

11 is the key that you use on both routers so that they can connect.

I hope this helps !

Hi sysexpert

Sorry, I got tottally sidetracked in setting up my VPN and forgot this question. Can you explain how to get the key in item 11 of my question?

Thank you for taking the time to help me by the way. I will grade the question this time, I promise.

You decide on a PSK ( preshared key ) text, I usually pick something random, at least 10 chars.

Needs to be the same at both ends.
