How to use the extra /29 subnet that was routed to my dynamic ip address from my provider on DSL

I'm currently using an Astaro Security Gateway as my firewall. It currently picks up it's external IP address dynamically, but it's always the same
I requested my ISP to assign me some more ip's so they "routed" a /29 to my external IP address
The problem I'm having is that the subnet they forwarded is completely different my external IP. so I'm not sure how I can use it to do NAT.

Any ideas what I have to do on my firewall in order to use this subnet??
