Having two subdomains on one public IP addres bheind pFsense router

I have one pubic static IP address.
I have my main domain register at local Internet provider and their DNS.
My main router is pfSense and behind it i have my local network. My WEB
server is in local lan and pfSense doing NAT (port redirect) WEB trafic to
local server.
Now I have needs for one more web server inside lan (on other local IP
addres) (etc mail server) and I have needs for one more domain or sub
domain whatever. Can I register my new domain under same public IP
address, and tell pFsenes router to do different redirecting of traffic
according to requested domain. I am planing to use both domens under HTTP
(80) port.
Is it possible to pFsense redirect to one local IP when request calling
domain.com and to do different port forwarding when request on the same
public IP adders calling subdomain.domain.com ?
If this is posibile whic one of Pfsense modules I shud install and
configure, and how?
