Load Balancing 2 web servers

OK have read the PDF on pfsense about load balancing. I want to load balance 2 windows IIS servers. The PDF make is sounds possible, but I can't seem to get it working.

I setup a 3 virtual machines, 2 with IIS on windows server. The last machine was a pfsense with 2 nic.

The WAN is set to 10.0.0.0/24
pfsense gateway 10.0.0.97
IIS load balanced IP 10.0.0.16

The LAN is set to 192.168.1.0/24
pfsense gateway 192.168.1.1
IIS1 windows 192.168.1.100
IIS2 windows 192.168.1.101

status > Load Balancer > Pools
show both IP 192.168.1.100 and 192.168.1.101 at 100%.

status > Load Balancer > virtual servers
show status "active" for address 10.0.0.16

But when I go to that 10.0.0.16 address I get connection refused.

I added the firewall rule...
IPv4 TCP source* port* list_of_IIS_servers 80 (HTTP) gateway* queue none schedule""

list_of_IIS_servers -> 192.168.1.100 and 192.168.1.101

Some of the google stuff I read talked about some type of gateway but did not give an example of how to do it.

Any suggestion on what I should try next?

@ssanders76

I got it working you need to add a virtual IP address (IP Alias) of 10.0.0.16/24 on the WAN.
