From Hentschel
The gateway on network B needs to be modified to redirect traffic destined for host hentschel via eth0 on host zm.home. We don't redirect all internet traffic via the tunnel, just what is destined for zm.home. On the Asus router, that looks like this:

At this point, a request for any host on network B that originates on host hentschel will be answered. At the same time, traffic for hentschel from network B will be directed there via zm.home. Note that the web server on hentschel does '''not''' answer since it's interface is only set to the public interface.
