ISP delegated /29 in addition to pppoe static IP address


I’m currently running blue+green+red, and I am currently looking for more information on how I can assign, if possible that CIDR amongst my green, and blue networks. I’m guessing it might have to be custom rules. I know the router IP address at the other end of my /29 delegation.

My ISP is Internode (Australia) provides me with a /29 in addition to a static IP address that isn’t part of that /29. I am happy to provide more information on request. Is it current possible with IPFire2 (with IPFire3?) to assign those static address to my Green and Blue networks without manually configuration?
