I can establish a VPN connection when connected directly to my router via an eth0 connection. Full network access which was what was desired woo hoo!
The problem is that I want to establish that connection via wifi as my raspberry pi is ultimately going to be away from my router. When I try and establish a connection to Hamachi it shows through the web interface that the pi is connected and when i do an ifconfig it shows ham0 connected. The issue is that it doesn't show a ham-br0 connection like it does when connected via eth0.
So I'm ultimately connected via wifi to my router and Hamachi makes the connection to the server but it's not bridging the two connections. Any help would be greatly appreciated to fix the issue. Almost there!
