[closed] Connect 2 machines where one is VPN connected and other is not

I have managed to share keyboard/mouse between 2 machines, of which only one of them is connected to VPN (OpenVPN client). Both machines are on the same subnet, running Linux, and connected to a Linux firewall running shorewall.

• The client is the machine connected to VPN (IP address 192.168.1.10)
• The server is the machine not connected to VPN (IP address 192.168.1.11)

Add the following to the /etc/openvpn/client.conf on the client:

route 192.168.1.10 255.255.255.255 net_gateway

Add to /etc/shorewall/interfaces on the firewall to allow LAN machines to talk to each other.

loc eth0 detect routeback

Finally start synergys on the server, and synergyc 192.168.2.11 on the client.

For additional security one can use a ssh tunnel to encrypt traffic. On the client:

ssh -f -N -L 24800:192.168.2.11:24800 192.168.2.11 synergyc localhost
