Public IP subnet config

I have an CCR1072 which is my main controller
I used to have a static IP form my ISP and everything was working fine.
I requested a subnet form my ISP and they gave me another 16 static ips
now I am having a some issues :

  1. how to configure the public IP’s that my customers get a different public ip form my range when reconnecting -i am using pppoe on radius- ( to make the public ip’s loop among the users)
  2. some of my PPPOE customers asking to have a static public IP on there router - how configure it?
  3. i want to connect another ccr1036 on SPF+2 and give it a public static ip from my range and to be able to control the bandwidth on it ( what i did is i created a bridge between SFP+1 - ISP- and SFP+2 and on the ccr1036 I configured the a static ip form my range and the internet started to work as expected , i also created a que for the ip that i used on the 1036 on the 1072 to limit the bandwidth but it worked with only the upload only and not the download - didn’t know why)

so please help ? and i am open for any suggestions or alternations
