Converting a /26 into multiple /29

Hello,

We have an AT&T ADI and were given a /30. Cool, we used that for our pfsense.
We were also given a /26 to route. Well, we only need a few IPs. Wanted to know if it is possible to convert a /26 into multiple /29 blocks on pfSense. Yes, I know I can’t use all the IPs in that instance. That is fine. Just looking to see if it is possible since I can’t ask AT&T for multiple /29 blocks on the same circuit.

Why is the requirement to break up the /26? What are you looking to gain by splitting them up?

Possible subdivide for if I wanted to slice out some of the internet for a few customers to colocate some servers or virtual machines.

AT&T will send all traffic for all those IPs to you , thinking its a /26, regardless of how you use then on the “LAN” side of your router. If you create multiple interfaces/VLANs with /29 (or /27, /28) subnets then it’ll “just work”.
