VPN between 2 Watchguards

[nervous2]

I have 2 Watchguard units but with VON capablilities the WG2500 have the added on feature, my wg firebox 700 is in Canada on a public ip of 207.136.***.*** while the WG2500 is located in Ohio with a PRIVATE IP address of 10.143.***.***. My obstacle here is that the Ohio IP is on a PRIVATE network. Can i initiate a VPN with this obstacle? if I initiate the vpn and use the x700 as the client what problems am i likely to face?? The network in Ohio is a workgroup while in Canada it is a domain with dual servers running windows 2000 Server.
Will all the computers on Ohio be able t access the internet going through thier own local internet?
My main goal is to map a few shared drives for everyone to see.

Can anyone here please guide me in how I can do this.

Im not sure - you surely need an external link in ohio to the internet to allow vpn. also im not sure about whether you can authenticate between a workgroup and a domain...

The fireboxes on both sides must have an external IP address for your VPN to work properly. We just set-up a branch office VPN with our UK office and they are working great. There is no way for you to reach the firebox if it doesn't have an external IP address.

Good luck,

If you have a Private IP, you'll run into a double NAT. Another router somewhere is placeing a wrapper on your packets, giving them a Public IP. I'd suggest using tracert to find out where and who, but I don't know what you can do from there. You'll need an un-NATted Public IP for VPN.
