Docker create ssh tunnel12/30/2023 ![]() ![]() This will silently create an encrypted SSH tunnel to RemoteSshServer and then use this tunnel in order to connect to your network router. Fill-in required information in order to connect to "RemoteSshServer".Open the "Network settings" section and check "Connect through SSH gateway (jump host).This address should be the one which will be used by "RemoteSshServer". ![]() Put your Cisco equipment address in the "remote host" field.In MobaXterm, just create a new telnet session.There is a simple workaround if you can reach a server behind the firewall using SSH: let’s say the server you can reach using SSH is called “RemoteSshServer”. It is sometimes hard to work with remote network equipments, especially when they only allow telnet connections and when telnet is disallowed in your company firewall. How to connect to my Cisco router or switch behind a firewall? This will silently create an encrypted SSH tunnel to ServerB and then use this tunnel in order to connect to ServerC. fill-in required information in order to connect to "ServerB".check "Connect through SSH gateway (jump host).put "ServerC" in the "remote host" field.create a new SSH, telnet, RDP or VNC session.Unfortunately, ServerC cannot be reached directly on the network, you have to connect to ServerB first, then from ServerB to ServerC. Let’s say we want to reach ServerC through SSH, telnet, RDP or VNC. MobaXterm makes it really easy to connect through a jump-host. How to connect to remote computers using a jump host Local applications should be compatible with this protocol and allow configuration of a "SOCKS proxy". Dynamic port-forwarding: same principle, but the dynamic tunnel allows connection to any remote hosts and any remote ports.Remote port-forwarding: this is the same principle, a tunnel is opened from local computer to jump host, but the aim is to connect from remote server to local computer. ![]() This picture shows the mechanism called “Local port forwarding”, but there are 2 other kinds of port-forwarding: Their connection will be automatically forwarded through the encrypted SSH tunnel, go through the jump host and reach the remote server on port 3306. In order to reach it directly, the client applications will have to connect to “localhost”, on port 12345. In the example above, the remote server is running a MySQL database on port 3306. A SSH connection will be established from “My computer” to “SSH server” (used as a “jump host”) and the local clients will use this tunnel in order to directly connect to the remote server. This screenshot explains local port-forwarding mechanism: local clients need to connect to a remote server which cannot be reached directly through network. If you are not used with SSH tunnels, here is a simple graphical explanation on how a simple SSH-tunnel works: Simple explanation of SSH tunnels and port-forwarding In all these situations, you will be able to achieve your goal easily thanks to SSH-tunnels.
