Connection / Port Forwarding

This category only appears if VanDyke Software's SecureCRT® 5.0 (or newer) is also installed.

The Port Forwarding category of the Session Options dialog allows you to configure secure connections to an SSH1

Overview of Port Forwarding

Port forwarding
The concept of connecting a logical port on a local machine to a port on a remote machine over a secure (encrypted) channel. All requests for services sent to the local port are then forwarded across the secure channel to the corresponding port on the remote machine. is a powerful tool that allows you to secure TCP/IP traffic using SecureCRT's SSH1 and SSH2 protocol support. This means that you can encrypt application data using protocols such as IMAP, POP3 and SMTP. For example, if you receive your email from an Internet Service Provider (ISP), you could encrypt the communication between your workstation running the email client and the ISP's SSH server.

In general, with any port forwarded by SecureCRT for an application, the application needs to be reconfigured to use the localhost or loopback address 127.0.0.1 as its application server address.

Locally forwarded connections

Name

Displays the unique identifying name for the connection
A data path or circuit between two computers over a phone line, network cable, or other media. .

Local Address

Displays the local port number for the connection.

Remote Host

Displays the remote machines hostname or IP address
Every site that is reachable on the Internet must have a valid IP, or Internet Protocol,address. An IP address should be entered as four numbers separated by period (.) characters (for example: 198.105.232.1). and the remote port.

Application

Displays the application to be run over this connection.

To create a new port-forwarded connection, click on the Add... button to open a blank Local Port Forwarding Properties dialog. To modify an existing connection, select that connection and click on the Edit... button to open that connection's Local Port Forwarding Properties dialog. To remove an existing connection, select that connection and click on the Delete button.

Do not request a shell

Select this option to have SecureCRT not request a command shell when attempting to port forward. This ensures that port forwards will work even if shell access is denied.
