multi public ip from isp

[mdwlater]

Hi, first sorry for my poor english...and Im neophyte for opnsense....
I need have multi public ips, my isp give me the "main" Ip: 217.133.1xx.xxx and the subnet ip: 217.133.2xx.xxx/29(5 ips usable).
In opnsense I create 2 interface, wan and lan, connection to internet is ok, connection to lan is ok....
but i can see only the "main" ip, I try to nat one-one but nothing:
 
   Firewall: NAT: One-to-One
      Interface: wan
      type: nat
      External network: 217.133.2xx.xxx/32
      Source: singole host or network: 10.10.10.x/32
      Destination: any

in web server(10.10.10.x) this ip not work

I try virtual ips and nothing again
Firewall: NAT: Port Forward and nothing again
Maybe I not make something good....you can help me?
Thank you

p.s. opnsense is my router, I not have fritz! netgear or similar....I install Opnsense in one pc with 4 lan
