Use the options in the Telnet Security page to select SSL/TLS security and proxy server options. A proxy works in conjunction with a firewall (often as part of the same system) to provide network security. A proxy acts as an intermediary to limit access between clients in an internal network and servers outside the network. Telnet, FTP, and SOCKS version 4.0 proxies are supported. If the SSL option has been installed, Telnet SSL proxies are also supported. If you have already selected Telnet as your Connection Type, you can access the Telnet Security page by choosing Settings from the Options menu. Otherwise, choose Session Type from the Options menu and change your Connection Type, then choose Settings.
To configure to use a proxy server
In the Telnet Security page under Proxy information, select your Proxy Type.
Under Proxy Address, type the Host name or IP address of your proxy server.
Under Proxy Port, type the port number of your proxy server.
If you use a Telnet or Telnet SSL proxy, type or select a command to send to the host when connecting.
If you provided connection information in the Telnet Connection - General page, your host name is automatically added to the command you select. The host port is also added if it is a number other than the default, 23.
For Telnet commands, host information is appended to the command you select. For Telnet SSL commands, it replaces variables in the command.
