m0n0wall protecting a whole VMware network

I talked about m0n0wall several times and you know: I love this firewall.
To celebrate m0n0wall anniversary and 1.0 release, a new Gallery section has been opened and an enthusiastic user, Bart Smit, sent an interesting configuration diagram where m0n0wall is installed on a VM and it protects all other VMs as well as HostOS.
