Inbound Load Balancing Question

[eprimaveri]

I have setup a pool of servers that are listening on TCP port 29000.  I have setup the virtual server as well.  For some reason the firewall is showing these hosts as being down on port 29000.  I have done a nmap and I see the ports open.  I have also telneted to the port without issue.

How does PFSense check to see if the port is listening on the server?
