SonicWall Router - VPN Tunnel

Hi Experts,

I’m working on creating a vpn tunnel to a 3rd party host.  The host is sharing their server among a few of the clients.  When setting up a vpn tunnel, the router tech informed me that an existing client is already using the same network addressing scheme as we are.

Is it possible to emulate another network and ultimately have it connect seamlessly onto our network?  This is a client\server configuration so the entire Lan Primary SubNet  will need to access the cloud resource.

We are on 10.0.0.x \ They are on 192.168.250.x

Not sure if this is correct, but I setup the VPN tunnel up to this point as:
Local Network is: should be 10.0.0.0, but I crated 10.0.15.0 thinking I can create a route translation
Destination is: 192.168.250.0

When I attempted to connect the tunnel, of course I get an invalid cookie error which means I don't know what I am doing.

Thanks for any help you can provide.

Couple leading questions.

Is it just one device on your end that needs to communicate with them?

If it's multiple devices on your end that need to access the remote end is the initiation of traffic always from your side?

"an existing client is already using the same network addressing scheme as we are'

This represents a problem when your LAN subnet is the same as that of another connection.

You example "We are on 10.0.0.x \ They are on 192.168.250.x" does not reflect that.

What am I missing here?

You can do NAT over VPN

@carlmd,

I thinking byd2k was referring to the 192.168.250.x subnet being the destination subnet. The local subnet of 10.0.0.x conflicts with some other branch already connected.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
