webserver load-balancing on LAN

[metal]

Hi,

I am trying to load balance a couple of web servers from the LAN side:
LAN IP is 192.168.10.1

1. Created a virtual IP "VIP" 192.168.10.10
2. Created a pool "LB01" that contains two web servers with IPs 192.168.20.1:8080 and 192.168.20.2:8080 and they are reachable by pfsense LAN interface
3. Created a virtual server with IP 192.168.10.10:8090 that points to "LB01" pool
4. I created a rule on FW to allow all traffic to VIP 192.168.10.10 on any service from any source
5. WebGUI redirect is Disabled

I can ping VIP 192.168.10.10, but port 8090 is not open on it, also when I look at the status of load balancer, it shows that virtual server is down.

pfsense version: 2.4.3-RELEASE-p1

thanks
