  Can you post a snippet of your configuration, e.g. for the virtual
server and some of the real servers?

  Yes, there is a lot of stuff about them that is poorly documented or
confusingly documented.

  I thought for several years that they were unable to have virtual
servers based on real servers which are not physically connected
through the ServerIron (which actually was broken functionality in
early firmware releases.) It wasn't until some people on this list said
they were doing just that that I started experimenting and discovered
how it had to be configured to make it work, using the source-ip
settings.  (The commands were documented, but how you have to use them
in a particular network topology was not.)
