Web server failover

[rcktboy]

I like to create a failover for my web server.

I added a monitor to check ip webserver (172.16.32.101)
(Added one later for offline page server to)
I added two Pools (also tryed one)
Pool one is webserver ip
Pool two is offline page server (172.16.32.104)
I added a virtual server (172.16.32.200)

And edited the HTTP NAT rule to go to the virtual server.

In the stats I see everything up and active, but as soon as I edit the NAT rule the websites on the server will timeout.

I also tried changing the virtual server ip to the Wan ip, but that also is not working

I'm running the 2.1 beta

Can someone help me out?
