I have one public 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 traffic to local server.
Now I need one more web server inside my LAN (on another local IP address) (etc mail server) and I need another domain or subdomain.
Can I register a new domain pointed to the same public IP address, and tell pfSense to do different redirecting of traffic according to domain? I am planing to use both domains 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 possible which one of Pfsense modules I should I install and configure, and how?
