As far as know, you can assign that public address to the other interface. In order to get those private address out on the internet you need to do some kind of ip nat statements (probably overloaded). Look here:
What you need to do is to configure Network Address Translation, a process which will result in your 10.x.x.x addresses being translated to a public address. You cannot route 10.x.x.x addresses on the Internet, so this is absolutely necessary to do.
Here's a sample config:
description * internal interface *
ip address 10.1.1.1 255.255.255.0
ip nat inside
description * external interface *
ip address 188.8.131.52 255.255.255.0
ip nat outside
ip nat inside source list 1 interface serial0/0 overload
access-list 1 permit 10.1.1.0 0.0.0.255
As per this config, all source addresses within 10.1.1.0/24 will be translated to the IP address of the serial interface using a process called port translation, which allows multiple internal addresses to be translated to a single public address.
As mentioned by the other posters, using a DHCP server is the best solution. You might want to reserve some addresses for any servers that you want on that segment. The rest can be dynamically assigned.
Here's a sample config for enabling DHCP on the router:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
