I'm a bit confused though my original ip was a /24 and now my new Ip's are /30 I hope this doesn't pose an issue.
That's not really a pfSense issue, it's between you and your ISP.
You use the extra IPs to create virtual IPs for pfSense. Then you can create port forwards that route traffic from the virtual IP to the LAN host.
For example, I have a block of 14 usable addresses, and I have a VIP - IP Alias for each one. When creating you port forward, you select the VIP as the Destination.
