Client allowing VPN

By stuart.johnson ·
A client of ours has offered to give our company a VPN connection to their network (NT). They are already set-up with VPN capability, but we are not.
I am told that our firewall does not support VPN (upgrade needed) and we use DHCP on our internal network (NT & W2K).
The question I am asking is:
How can we connect to our clients network without upgrading our firewall?

Client allowing VPN

by Joseph Moore In reply to Client allowing VPN

First off, if your firewall is not compatible with everything you need to enable to let a VPN connection through (including IKE, which is probably your problem) then you have got to upgrade it. Nothing you could do behind the firewall will matter ifthe firewall itself won't work with VPN.
That said, say your firewall is upgraded and able to pass VPN traffic. You will need to set up a static IP address to the internal machine that will be the VPN client; don't use DHCP to dynamically assign the IP address to this one system. The system can still have an internal IP address, but it must be static.
The reason is a "1-to-1 NAT" is what you will need to set up on the firewall. You will have to point a single Internet public IP address on theoutside of the firewall to the internal static private IP address on the system that will be the VPN client. If your firewall can do the 1-to-1 NAT, then you should be ok.

hope this helps

Check out the documentation on your firewall on how to set this all up.

This question depends on how often, how long or how much data is needed from them.

If it's a once a day file sync maybe you could do it over modem. If you need access to their network all the time and are transfering big files, then a vpn connection would work best. You could try setting up a vpn through W2K server. If their firewall supports software VPN then you could install the software on your machines and your people could connect whenever they wanted to.
