pfSense Captive Portal passthrough port and ip address

If you need to allow certain application to run along with the log-in screen, for example 

a chat box on the pfSense's Captive Portal. you need to first allow a  specific port or an IP Address to passthrough a the Captive Portal.

Go to terminal

 nano /etc/inc/captiveportal.inc  

use ctrl+w to find

Any rule after this line

 # redirect non-authenticated clients to captive portal  
 add 65532 fwd 127.0.0.1,{$listenporthttp} tcp from any to any dst-port 80 in.....  

will get blocked so it should be added before it's blocked.

let say I want port 5900 to open in captive portal, I should:

 add 5900 pass tcp from any to any out  
 # redirect non-authenticated clients to captive portal  
 add 65532 fwd 127.0.0.1,{$listenporthttp} tcp from any to any dst-port 80 in.....
