You have chosen to have this virtual private network server
automatically assign client IP addresses, or assign them from a
DHCP server. However, the network connection for this server
is configured to have a static IP address. 

If you want this server to assign IP addresses automatically or
 from a DHCP server, you must ensure that the server's static
address is compatible with the addresses assigned to dial-in
clients.
