Routing globally unique ip addresses

We are a small service provider, hosting service etc, we acquired a range of /24 public addresses from our ISP which so far have been used for web servers, I have come accross some 3rd parties who use globally unique ip address on both pulic and private side of the network.

If I route global address on private network how will NAT work when they need to access the internet?

Routing globally unique ip addresses

you will need to break your /24 is small subnet.

Then you can route some portion internally.

Regarding NAT, either you can do NAT Exempt, so that traffic go with out NAT and since IP are already public so no issues.

or again on your Firewall you can do static identity NAT.

I need to route major portion of subnet internally 

diagram attached, can I brreak /24 into small subnet for firewall interface say 213.249.128.2/29, if I route rest internally then I need a route on firewall to say 213.249.128.x is inside, how will route out work if the route is pointing to next hop

internal?
