How to Enable Web Server Load Balancer

[inayat1985]

hey, I been trying to work 2-WebServers behind multi-Wan setting, but no succes.
MY network setting is as follow:

WAN : 210.2.140.* ( if i Plug Cable direct into PC, then Public IP can asign directly to PC no need for LOCAL IP, so thats y using Public ip on WAN)
Opt1: 172.16.1.254
Opt2: 172.16.2.254
LAN : 172.16.0.254 (Pfsense 2.0.2 GUI)

Web1: 172.16.0.14
Web2: 172.16.0.15
I can access both Servers IIS localy

I tried this How to (http://www.howtoforge.com/how-to-use-pfsense-to-load-balance-your-web-servers )and assigned Virtual IP: 172.16.0.5:80, and tried to localy access it like http://172.16.0.5/web .. but didnt work, http://172.16.0.14 and 15/web work fine,
then i tried to access it from different Network . i did NAT/Firewall rule for 172.16.0.5 on Opt2: (3rd DSL as i didnt wanted to disturb the WebServers for Customer on other two DSL's, so for testing i used Opt2) but no success, .

Can anyone please tell what i am doin wrong…. thank you..
