Sena STS Series User Manual page 31

The IP filtering feature for access to Telnet console, SSH console or Web server may be enabled
or disabled. The factory default of the filtering feature is "Enabled".
The user may allow a host or a group of hosts to access the STS Series for configuration. The
user must then enter the IP address and subnet of access. Any user on a remote host must stay in the
specified subnet boundary to have the configuration access.
To allow only a specific host to have configuration access to the STS Series, enter the IP address
of the specific host and just give 255.255.255.255 for the subnet
To allow any hosts to have access to the STS Series, give 0.0.0.0 for both of the IP address and
subnet. Refer to Table 3-2 for more details. The device's default settings for allowed remote hosts for
configuration is "Any".
