In the Hostname or IP field, type: 127.0.0.1.Set the Type field to SOCKS version 5 (no authentication).Specify a Name for the firewall (for example: Gateway Firewall).Press the Add button and use the following configuration guidelines.Open SecureCRT's Global Options dialog and select the Firewall category.To set up a global firewall/proxy in SecureCRT: Need to be created so that other SecureCRT sessions can use the SSH Up in the "Master" session, a global firewall configuration will Enable the Auto reconnect option so that if the connection goes down unexpectedly, SecureCRT will automatically attempt to re-establish the connection.Ĭonfiguring a Global Firewall/Proxy Setup in SecureCRT.Enable the Send Protocol NO-OP option and specify an interval less than the idle timeout of the remote server or remote shell.Since this "Master" session will need to be connected and remain connected for all sessions that use the SSH SOCKS proxy, it would also be a good idea to make the following configuration changes to the "Master" session (both options are found in the main Terminal category of the Session Options dialog as depicted below):.Enable the Dynamic forwarding using SOCKS 4 or 5 option (the other fields in the Remote category will not be used in this configuration).Since this port forward will be used as a SOCKS proxy, it makes sense to specify 1080 (the standard SOCKS port). Enter a value for the Local / Port field by entering a listening port value.In the Name field, specify a unique description.Select the Connection / Port Forwarding category, and then press the Add button.Open the Session Options dialog for your "Master" session.Modify your "Master" session to have a dynamic port forwarding configuration.Test your "Master" session to ensure that you can successfully connect and authenticate to the gateway SSH server.Name this session "Master" session (you can choose another name, but "Master" is used in this documentation as an example).Make sure you set the Hostname field to match the hostname of your gateway SSH server.Set up an SSH session to the gateway server in SecureCRT.The configuration of a dynamic port forward is accomplished using the following steps: Note that the term “gateway server” used here refers to any SSH server that supports port forwarding functionality. A dynamic port forward is a listening port which acts as a SOCKS proxy that is automatically created when the “Master” session is used to connect to the gateway server. Session will then need to be modified to have a dynamic port forward configuration. Session that can successfully connect via the SSH protocol to the gateway
The first step is to configure a "Master" The graphic below illustrates this concept: Configuring the "Master Session" to the Gateway Server
That are located behind the gateway server. Sessions can then connect through the "Master" session's SSH SOCKS proxy to remote servers This tip focuses on using SecureCRT's dynamic port forwarding functionality with a "Master" session to create an SSH SOCKS proxy associated with a connection to a gateway server. Have their connections forwarded through this SSH SOCKS proxy and on to the desired (including other sessions established with SecureCRT) will be able to Using an SSH SOCKS proxy, any application that is SOCKS 4 or 5 compatible To reach all machines within a remote network (behind the gateway). SecureCRT provides the ability to create an SSH connection with a dynamic port forwarding configuration that can then be used as a SOCKS proxy This can be problematic and time-consuming,Įspecially if more than two jumps are required. Server, and then issue another SSH connection from that server to each One solution would be to establish an SSH connection to the gateway Of devices that reside in a remote network behind a single gateway server.
