One possibility is that you cannot reach the port number of the service.
This would explain why a ping or telnet to the VIP works, but the service
itself is seen as failing. Try telneting to that sepcific port number
as well. If telnet can't reach it, piranha can't either.

This has been discussed here before -- I'll let others handle it.

I'm not sure I understand either. Again; it has some of the signs that
it's a problem reaching the service port rather than the server.

Make sure, BTW, that you aren't actually reaching web servers running on
the router itself. Some people have run web servers on the routers (so the
piranha GUI can configure the servers for example), and have mistaken their
attempts at connecting to them (via the VIP) as a successful connection to
a real server web service.
If you still believe you are having problems specific to piranha, could
you log an entry in http://bugzilla.redhat.com/bugzilla so it can be
tracked?
