Communicating between two companies both with Private addresses

[surfbum99]

Hi,

Can someone tell me the solution if I want to be able to get to a private addressed network in another company and still use the network in our company which is also on a private address range?

Is it a case of using a VPN?

Are you saying that both IP private ranges are the same?

 

[surfbum99]

Yep, does this mean a Extranet VPN can't be used?

Or is it the case someone has have a public address and use a VPN client?

 

[chieftan]

Probably your second suggestion.

As you know, you cannot have 2 same ip addresses on the same network. You will need to perform NATting of some sort and Remote VPN access......

You need to configure 2-way NAT between both source and destination devices. The following URL from Cisco goes into more detail about this with some configuration examples:
