IP address problem

Hello,

I have a problem public ip it.
my Internet connection has 8 ip adressen. (xxx.xxx.xxx.xxx/29)
I have got 128 new IP addresses now and wanted to use these. (NAT 1:1)
The ip addresses’ area is xxx.xxx.xxx.xxx/25
how can I solve this?
if I an IP address give the Internet interface to, this is attainable over the Internet.
If I liked to make NAT 1:1, I can do nothing more.
if I make a traceroute, I arrive up to the MT and not get further.
Can you help me?

Sorry for my bad english
