Have two offices that currently connect using terminal services from the remote office to the main office. Both have a dynamic IP address at each end, although the IP address for the two Linksys routers is always the same. Looks like this:
Main Office: 188.8.131.52
Remote Office: 184.108.40.206
The Remote Office (Win 2000 Pro machine behind a Linksys router(non VPN type))logs onto a Win 2000 server via Terminal Services. Everything works great.
The router at the main office was giving some trouble so it was replaced with a Linksys BEFVP41 VPN Router. Got it all set up and terminal services still works from the remote office to the main office. Decided to try and set up a VPN but can't seem to get it to work. Followed all the tutorials I could find on the web and in the instruction manual but can't make a VPN connection. Here are the VPN settings from the Main Office new VPN router:
Tunnel 1: SSMaintenance
This Tunnel: Enable
Tunnel Name: SSMaintenance
Local Secure Group: Subnet IP:192.168.1.0 'This is the end where the WAN IP is 220.127.116.11
Remote Secure Group: Subnet IP: 192.168.2.0
Remote Security Gateway: ANY (This gateway accepts request from any IP address!)
Encryption: DES is selected
Authentication: MD5 is selected
Key Management: Auto. (IKE) is selected
PFS (Perfect Forward Secrecy) checkbox is selected
Pre-Shared Key: this is about a 10 digit alpha-numeric string
Key Lifetime: 3600 Sec.
The Remote Office doesn't have a VPN router. Using Windows 2000 as the client to connect to the VPN router at the main office. Appendix C in the manual had a step by step for configuring the IPSec between a Windows 2000 and a Linksys Cable/DSL VPN Router. I followed all the directions exactly, including entering the WAN IP address of each end in the correct places.
My question, finally, is that I'm not sure what to put in for the "Remote Secure Group" and the "Remote Secure Gateway" values on the VPN router, can anyone explain what these are? Also, to make a VPN from the client do I have to specify a domain name or can I just use the Username and Password to logon to the private network that sits at the Main Office behind the VPN Router?
