I've several nets:
1. internal service net, only available from/for the hostnode
2. internal LAN with intranet services for my users
3. DMZ
4. external IPs

The host node should only be accessible in net 1, I don't want any 
routing or firewalling inside the hn, there should be no connection f.e. 
to net 4

In the mentioned article the are two advantages: security and 
performance
