[Quoted] [Quoted] It still looks possible using ssh tunnels. Try to make a ssh tunnel that connects C2 and WS and one that connects C2 and S. The local ports on C2 need [Quoted] [Quoted] to be the same (output port -> listen port). Doing so enables access from WS to S using a tunnel over C2.
[Quoted] On this very moment I am connected to a database running inside a LAN having a [Quoted] non routeble ip address using a tunnel over a machine that is behind a nat [Quoted] firewall. It looks a bit the same. ( I am working on a machine in an other lan [Quoted] where I have a private IP that is also not routeble over the internet) see:
