This risk exists. However, for example the Windows 7 IKEv2 client can
handle such conflicts surprisingly well, usually a user won't notice it.
Of course this might not be true for other clients.

I don't think there is a real solution for that problem. Probably it is
a good idea to choose an address range not commonly used. If you think
anything in 10.0.0.0/8 or 192.168.0.0/16 is not really an option, you
might go for a subset of the third private range, 172.16.0.0/12, which
might be less commonly used.
