Multiple Webserver, one public IP
-
I have PFsense as my firewall/router. The problem is I want to host two webserver using 1 public IP
on PFsense NAT I use different ports. One is 80(1st webserver) the other one is 8081(2nd webserver).
Within our LAN it works but when accessing it outside it fails.
Is theres something that I must do besides configuring the NAT?
Thanx

you have to access it via port on your url from outside
http://something.publicdomain.tld
would access default port 80 and and your forward of port 80 to 1st webserver
if you forwarded 8081 to 2nd server, then you would access via
http://something.publicdomain.tld:8081
if you want to access via some different name, then you would have to use a reverse proxy on pfsense to know that
name.publicdomain.tld goes to webserver 1, and other.publicdomain.tld goes to webserver 2. If using a reverse proxy then both servers could be on port 80. And would not be needed in the url
If not using a proxy then the only way to access different webservers behind your nat is to use different ports like what your doing. but you have to spell out that other port in the url used to access it.

You could use Apache's virtual server parms so you can keep using port 80 across multiple websites on a single IP.

^ yup that would be only 1 webserver though behind pfsense.
Nothing running on the webserver would allow for pfsense to send it to different webserver, that has to be done with reverse proxy on pfsense.

Reverse Proxy.
the reverse proxy hands all incoming connections and based on HTTP headers would direct to the LAN server you set it yo.
