Usage Guidelines
Use the firewall command to implement port filtering on the WLSE. To configure
an Ethernet port for secured public access, use the public option. To configure an
Ethernet port for local access, via a LAN or VLAN, use the private option. To
dissable icmp, Telnet, ssh, snmp, https, or to deny connections to the SSL HTTP
port or the HTTP 1741 port, use its corresponding option.
Example
The following is an example of a secure Ethernet port configuration:
• The Ethernet 0 port is connected to the Internet, and is configured to be
accessible only via HTTPS by entering the following command:
firewall eth0 public ssh 1741
• The Ethernet 1 port is connected to an internal LAN or VLAN, and is
configured to be accessible via any of the supported protocols by entering the
following command:
firewall eth1 private
An on-site user has full access to the WLSE, but an external user can only
access it using a secure connection.

name.
