seems to be ok, although I don't yet know how the configure.pl works
in great detail.

Hmm, I honestly don't know, I think only Joe knows the answer. I did a
quick
perldoc ./configure.pl and around line 700++ I found a suspicious note:
PERSISTENT CONNECTIONS and LINKED SERVICES
Some services need to be set up with persistence. This is
handled automatically for you. This section explains how
it works. You can skip this section if you like.
Single port services (eg telnet, http) can be assigned to
any real-server. The client at the conclusion of one
connection (session) can be re-assigned to a different
real-server for another connection without any effect.
These service do not need persistence.
But then Joe mentions something about linked services and I didn't
quite follow that one:
LINKED SERVICES
Multi-port services e.g. ftp (port 20,21 ie ftp,ftp-data)
or http/https (where connections to port 80 and 443 need
to go to the same real-server) are called here linked
services. (For VS-NAT, linking ftp and ftp-data is
handled by the module ip_masq_ftp, which has to be loaded
at run time.)
For all other services/forwarding methods, linking of
services is handled by LVS persistence (which could
alternately be called "port affinity"). Although we only
need to link these specific pairs of services, LVS
persistence links all services on the real-server, not
just the ones we need to link.
Thus if any of the persistent_services (ftp or https) are
found in the SERVICES line, then all services on that
real-server are tied together. Once a client connects to
that server for any service, all further connections for
any other service from that client will go to the same
real-server.
I'm a little bit puzzled myself actually. Let Joe clarify things here :)
Sorry I cannot help you right now,
