Site-to-Site VPN with Overlapping IP address

[OHITS-OPS]

I have a situation with a customer of mine, in that, we are trying to establish a site-to-site VPN but we have the same IP address as our customer, i.e. our customer is on IP 10.0.1.0 /24 and we are also on IP 10.0.1.0/24.

Now, can someone please tell me what needs doing to achieve this, if it is at all possible? I would be very grateful for a quick response.

Many Thanks

Aleksey,

Thanks for the link, but I need to know how to setup a site-to-site VPN when there is overlapping IP addresses involved and what the configuration is, if possible.

Basically, our end LAN IP is 10.0.1.0 /24 and our customer end IP is 10.0.1.0 /24 - so how dou I setup a site-to-site VPN ??

Many Thanks for your help on this.
