An Alternative Tunnel: VPN - PPP Tunneled Over SSH. Please see the article: "Using VPNs With NST" on how to create alternate secure tunnels using NST and SSH connections.
The SSH connection is used by the application to connect to the application server. With tunneling enabled, the application contacts to a port on the local host that the SSH client listens on. The SSH client then forwards the application over its encrypted tunnel to the server. Then using this connection as a tunnel we can connect to any machines at home by addressing them with local sub-network address (such as 192.168.x.x). So the high level steps are: Open a putty session and configure it to act as a tunnel. From this session connect to your default SSH server at home. Step 1: Establish SSH tunnel. Pick a temporary port between 1024 and 32768 (1234 in this example). Port 22 will be used by scp. $ ssh -L 1234::22

Jul 08, 2020 Tunneling protocol - Wikipedia Tunneling a TCP-encapsulating payload (such as PPP) over a TCP-based connection (such as SSH's port forwarding) is known as "TCP-over-TCP", and doing so can induce a dramatic loss in transmission performance (a problem known as "TCP meltdown"), which is why virtual private network software may instead use a protocol simpler than TCP for the Set up SSH tunnel for private browsing using GCE
Jul 01, 2019 · The workaround is to use an SSH tunnel to wrap another layer of encryption around your VPN traffic, disguising its origin so you can access the internet more freely. The main reason you’d want to use an SSH tunnel alongside your OpenVPN traffic is your VPN is being aggressively blocked.
If you can connect to your SSH server from the hotspot you can tunnel forward a local port to the VPN server. Assuming the VPN is available over TCP: ssh my-raspberry-pi -L9000:vpn.example.com:openvpn`. It won't be very efficient however. If your VPN is using UDP, I don't know any clean off-the-self way to tunnel UDP datagrams over SSH. Some apps (such as VNC clients) have built-in SSH tunnelling capability to get around this, but if the apps you're using don't include it, the only option (short of jailbreaking) is to use the built-in iOS VPN capability. It doesn't support SSH, but it does support L2TP/IPSec, PPTP, and some other variants. The easiest why to tunnel all traffic through SSH similar to a VPN is to use the sshuttle package. First, install the package: sudo apt-get install sshuttle Then connect to the SSH tunnel and redirect your default route to go through it: sshuttle -vv --dns -r username@sshserver[:port] 0.0.0.0/0 You can do this using ssh. ssh -L 80:remotehost:80 user@myserver You will have a tunnel from your local port 80 to the remotehost port 80 then. This does not have to be the same as myserver. To make that transparent you should add an entry to the hosts file. If you don't do that vhosts will not work.
