Again, please take a look at the message I posted earlier in the week.
If you can't find it, e-mail me and I'll send it to you directly.
The idea is that the nodes have to be on a distinctly different
subnet than the rest of the world. The LinuxDirector acts as a router
between the networks. This should apply even in the case of tunnelling.
I've never done tunnelling before, but I would assume the following setup
would work.
195.134.208.27 netmask 255.255.255.0 LinuxDirector outside
interface (the interface the world sees)
195.134.1.1 netmask 255.255.255.0
LinuxDirector inside interface (the interface the slaves see)
You'll notice that the inside interface is on a different network
(195.134.1.0) than the outside interface (195.134.208.27). When a
packet arrives that isn't addressed to the LinuxDirector, it checks to
see if it belongs to any OTHER networks it's connected to. If both
interfaces are on the same network (195.134.208.0) it drops the packet
in the input portion of the network code. The port forwarding happens
in the middle of the forwarding portion of the network code and will never
be executed.
The nodes should be configured something like the following.
Someone should verify this.
195.134.1.11 Node 1 inside interface
195.134.208.51 Node 1 outside interface
195.134.1.12 Node 2 inside interface
195.134.208.52 Node 2 outside interface
I hope this helps.
Cheers,
Matthew
P.S: Wensong, it's time to start a FAQ. I'll write up this explanation
in HTML, possibly with pictures, and I'll send it to you in the next week
or two so you can add it to the website.
