Public IP through site to site VPN

I have been asked to setup a site to site VPN with another company. The other company will only accept a public IP through the VPN. Will this be done through a 1-1 NAT? Configure the Public IP on another interface and then route that through the VPN? How can this be accomplished?

    Will just a single device/IP addr be used at your end to get to the other end?
    If so, 1-to-1 NAT will work.

    Yes, 1 user needs to access a server on the other end.

    So for the 1-1 nat, do I put the ip of the internal user for the Host IP?
