I have got a small network consisting of a terminal. Each one has a PPPoE link to an Ubuntu PPPoE server. This network is working fine, and each terminal can ping every other and the internet - all via the PPPoE server.
I have another network, which I want to be able to ping the terminals from. This network is not in the same building, and I need a tunnel into it. I would like to use Hamachi for this, as I am fairly used to setting it up etc, and the Ubuntu PPPoE server has the Hamachi client installed and setup.
I just need any PCs in the Hamachi network to be able to ping the PPPoE client terminals, but adding a route to the PPPoE subnet through the Hamachi link does yield any results :(
PC1 o====o Hamachi o====o PPPoE Server --------> terminal 184.108.40.206 220.127.116.11 172.16.2.1/24 172.16.2.50
route add 172.16.2.0 mask 255.255.255.0 18.104.22.168
On the PPPoE server, TCPDUMP shows pings coming in from PC1 if they are directed to the Hamachi IP address, but to anything else they dont show.
