I am new to pfSense so please be kind.

I have setup pfSense but I need help setting up routing so please see below IP address have been changed to protect the config.

This part is setup in pfSense and works fine.

WAN address is

15.123.205.236 - Network - unusable
15.123.205.237 - Default gateway to our up stream provider.
15.123.205.238 - Our pfSense WAN port.
15.123.205.239 - Broadcast - unusable

Subnet 255.255.255.252

pfSense LAN IP = 10.10.1.254

This is the part I am not sure on how to setup
I have a routed subnet. which I need to NAT to servers.

65.69.10.144 - Network - unusable
65.69.10.145 - NAT to 10.10.1.1 ports 25,80,443 - remote.acompany.com.au
65.69.10.146 - NAT to 10.10.1.2 ports 3389 - rdp.acompany.com.au
65.69.10.147 - spare
65.69.10.148 - spare
65.69.10.149 - spare
65.69.10.150 - spare
65.69.10.151 - Broadcast - unusable

Subnet 255.255.255.248

all workstations should be able to browse the internet from 10.10.1.1 - 253

Please help me get the second part working.
