We have an old ServerIron XL that we want to use for one of our clients 
however I am having issues getting the cluster setup with DSR.  The real 
servers are showing as bound to the VIP, but the load balancer doesnt 
seem to be responding to arp requests for the VIP so traffic never makes 
it to the LB. I'm sure it's something very simple, but any help is 
appreciated
Here is the config
