I would use an fwmark service for that. Then, when I want the client to be
directed to the service, I'd add the iptables rule, and I just have to remove
it to close the pipeline. The fwmark entry could stay in the LVS
configuration; you can even define one fwmark service per realserver and play
with the mark value to redirect the connections to the needed realserver.

Any other idea?
