VPN access to clients in the same IP range

[dinjan82]

Our business partner has a collocated data server with no public access and only VPN access. We are trying to establish VPN connectivity to the data server.

Our LAN IP range is 192.168.1.0/24. Our business partner has another client in the 192.168.1.0 range already connected to the data server via VPN.

My question is, can we establish VPN connectivity to the data server even though there is another client in the same IP range connected to it?

If not, what are the alternatives? Please note, neither us nor the other client in the same IP range can change our IP ranges.

Your feedback is much appreciated.

An IP address must not conflict or you will see problems. I generally assign my remote users like this;
Tom= 192.168.1.0/24
Dick= 192.168.2.0/24
Harry= 192.168.3.0/24

A different method would be to assign them a static address at the high end like 192.168.1.24 and keep track of the assignments as you add them from the top down; 192.168.1.23,22,21 etc... This must be balanced with the number of systems your router is assigning through DHCP as they will increase starting from the router=192.168.1.1, then it will dynamically assign 2,3,4 etc...
