home pc - office using VPN

A nice way to connect to the office instead of vpn is remote desktop client, all you need from your office is an ip address, and you can download remote desktop client from microsoft.com
The office must have a windows 2000 or 03 server.

For the vpn, is your router a vpn router? you will need ip addresses from your office in order to connect, what os is your computer at home?

YES I HAVE VPN ROUTER ALSO COMPANY GAVE ME IP ADDRESS NOW MY HOME PC IS XP AND ALSO COMPANY IS RUNNING WIN 2K SERVER

1. depending on the policy that they have set up at the corp office, you might need them to make a security policy on the firewall or where ever they have hte vPN terminating. From there, you need to have a policy on your firewall/router that points there there IP address with the exact same setup, only diffrence is your firewall would have there firewall name in it and there wouldn't have yours. IF they didn't set this up, the only way you could possible connect into the VPN is to have a software program but you still need security keys and most likely the program that came with the VPN deviuce at there location.

First of all you must make sure that your router and the work router can talk to eachother. This means do they use the same encapsulation and authentication.

For instance are you going to use L2TP or PPTP or IPSec to encapsulate the packets you are sending between your home and the office.

Once this is sorted you must setup a VPN entry on both routers. If both routers are VPN capable there should be an area to type in your computer name and public and private IP addresses. You must do this at both locations.

Now you must setup authentication, pre-shared key is an easy way. Which is simply having a password on each router that matches the other. Once a connection is made they check to see if they both use this password and connect.

You will both need static ip addresses given to you by your ISP to make things easier. you can however install client VPN software on each machine and account for the changing ip address, although at least one has to be static.

I suggest you ask for professional support as setting up a VPN can be a daunting task.
