Telnet Access
Telnet allows access to the BSGX4e unit through a remote terminal session. Telnet
access requires the following:
The workstation on the WAN or LAN must provide a Telnet client (for example,
Tera Term Pro, Windows telnet client, or Linux telnet client).
As initially configured, the Telnet server in the unit is enabled, and the firewall
allows Telnet access from the WAN.
If the initial unit configuration is changed, the following reconfiguration can be
required:
For Telnet access from the WAN, the firewall must allow Telnet traffic
terminating at the BSGX4e device. This requires a security policy for TCP traffic
to the Telnet port (The default Telnet port is port 23). For more information
about security policies, see “Firewall Security Policies” (page 130).
The Telnet server on the unit must be configured and enabled as described in the
following section “Telnet Configuration Command” (page 34).
Telnet Configuration Command
To change the Telnet configuration, enter the following command:
> config service telnet
Table 3 describes the parameters for config service telnet.
