Client in an unknown network

dometec

Hi all,
I need to create a small vpn beetwen office and multiple clients in other locations. My problem is that I don't known the address space of my clients network.
I was thinking to create two server network (es. 10.0.0.x and 192.168.0.x) and let the client to choose the right server to connect (with a script may be...).

Is it achievable?
There are other better solutions?

Thank you,
Domenico

Yes, the client's private networks belong to different companies, each of which has arbitrarily chosen a private network address for their internal network (10.xxx, 172.16.xx, etc.etc.) that I don't known...
Then I can't have a single network address for VPN, because the customer could have the same address for its internal network.

Thank you
Domenico

10.0.0.0 - 10.255.255.255 = 16.5 million possible networks .. just choose an obscure one ...

mmmm

10.x.x.x/8 It's one and only one network segment. If the network client use a 10.x.x.x/8 the VPN can be only 172.16-32.x.x or 192.168.x.x.

Are you agree?
