I have been running freevrrpd and pen (http://siag.nu/pen/ or in ports) 
for HA web services.

My setup was a firewall/gateway consisting of more than 1 machine using 
freevrrpd thus enabling failover for the firewall/gateway. I write 
firewall and not firewalls since freevrrpd creates a virtual ip that is 
failover'ed between the machines.

On the firewall/gateway pen were running and pointed towards the web 
servers. Pen can point at as many web servers as you like and balances 
the load between them in a very simple way. If the web servers are 
identical in setup they become redundant. DNS loadbalancing is very 

Good luck!
