Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      To clarify vpn: this machine does not even have a non-vpn ip. The router that established the vpn is multiple nat & bridge hops away....

      How do you connect to the VPN? If tunnel runs across the internet at any point, you can leak. Try run dig from diff locations.

      Ethernet bridge over ssh. The ssh session and ip network it's over is completely physically isolated from everything else.

          i.e. there's no way to send an ip packet from the router at this side of vpn, or anything behind it, to the ssh client host.

          This is where I get confused. If you can’t send IP to the ssh server, how do you establish a TCP session?

          The ssh client providing the bridge is a physically separate machine. Its eth0 is bridged to tap.

          The router machine & stuff behind it are plugged into that eth0 which has no ip addr, only bridge. No way to send ip packets to it.

          Everything between this rj45 jack and other end of the vpn are a big black box.
