for that purpose, we have a 2nd routing table running on the nodes. The 
trick is to mark port-80 traffic with iptables and forward exactly that 
kind of traffic to the load-balancer using an ip rule.

This makes it possible to add another http vhost on a different port 
which can be used to directly access the server.
