Realservers cannot access sites on virtual IPs

[Peter Brownell <peter_brownell@xxxxxxxxxxxxxxxxxxx>]

Hi,

Although I imagine this issue has been addressed previsously, I have no 
idea what lingo to use in my quest for info. So, if this is an old 
issue, i'd appreciate a pointer.
I have two seperate web clusters running behind my load balancer. I 
can't get them to see the public addresses of the sites they host. What 
do I need to do to get around this ?
I am using NAT, currently on a 2.4.2 kernel.

Thanks
Peter
