How can I NAT, DMZ, or Port forward routed IPs?

[torontob]

Hello,

I have one Alix2d13 (Three NIC ports) pfSense in production with the following network structure:

WAN Port from ISP:
Network: 39.39.39.152/29
Gateway: 39.39.39.153
Mask:    255.255.255.248
Usable:  39.39.39.156 to 39.39.39.158
WAN Set To: 39.39.39.156

Routed IPs to 39.39.39.156:
Network: 59.59.59.32/27 statically routed to 39.39.39.156

So, on vr0 or LAN-1 I have setup the /27 subnet and my DHCP for that port gives out all the IPs possible from the /27 subnet to my endpoints.

I also have vr2 or LAN-2 setup with 10.10.10.0/24 subnet which supplies the same endpoints for my private access.

My Questions/comment:
I am assuming that since all the IP sources are different I can have all the 65535 ports forward to a single endpoint and that I can do the same for every other IP in the /27 subnet simultaneously. Meaning I can do total of 65535 x 30 (30 is number of my usable IPs in /27 subnet).

Is that true? or given the way I have fixed the network structure I would only be able to port forward port 80 for example to only one endpoint?

The reason why I am asking this is because I am just checking the NAT section and when I want to create a NAT port forward it doesn't ask me for Source IP so I am wondering if I limited?

Thanks
