5. Other security features available only through JetDirect
Some security features are available only after installing a JetDirect 640n or similar internal print server.
4.1 Access Control list
This feature lets you determine the access control list (ACL), which is used to specify the IP addresses on your network
that are allowed access to the device. The ACL is normally used for security purposes and supports up to 10 entries.
The device blocks communications from all other addresses. If the list is empty, any system is allowed access. By
default, host systems with HTTP connections (such as web browser or IPP connections) are allowed access regardless
of ACL entries. This allows hosts to access the device when proxy servers or Network Address Translators (NATs) are
used. However, unfiltered access by HTTP hosts may be disabled by clearing the Check ACL for HTTP checkbox.
Host systems that have access are specified by their IP host or network address. If the network contains subnets, an
address mask may be used to specify whether the IP address entry is for an individual host system or a group of host
systems. For an individual host system, the mask “255.255.255.255” is assumed and is not required.
CAUTION! You may lose your ability to communicate with the device if your system is not properly specified in the list,
or access through HTTP is disabled. If communication with the device is lost, then it may be necessary to restore the
network settings to their factory-default values.
4.2 802.1X Authentication
802.1X is an IEEE Standard for port-based Network Access Control. It provides an authentication mechanism for
devices that want to connect to a LAN.
For most 802.1X networks, the infrastructure components (such as LAN switches) must use 802.1X protocols to
control a port's access to the network. If these ports do not allow partial or guest access, then the print server may
need to be configured with your 802.1X parameters prior to connection.
To configure initial 802.1X settings before connecting to your network, you can use an isolated LAN, or a direct
computer connection via a cross-over cable.
The supported 802.1X authentication protocols and associated configuration depend on the print server model and
firmware version. For more information on 802.1X features please visit here.
