3.7 Disable protocols
In some cases you might want to disable all protocols that you do not plan to use to access your printer. For example,
you might prevent users from sending files via ftp or connecting through telnet to manage the printer network
settings. You can disable unused protocols through the Mgmt. Protocols option in the Embedded Web Server, or
Network Enable Features in Web JetAdmin.
3.8 IPSec
A Firewall or IP Security (IPsec) policy enables you to control traffic to or from the device by using network-layer
protocols. Either a firewall or IPsec / firewall pages will appear, depending on whether IPsec is supported by the print
server and device. If IPsec is not supported, firewall pages will be displayed and a firewall policy can be configured.
Please note: Before you enable a firewall or IPsec policy, you should make sure that access to your configuration
management settings is secured (for example, through an administrator password). This will ensure that your policy is
not easily disabled through Telnet, control panel menus, or other management tools.
Firewall. Use this page to view or configure a firewall policy. A firewall policy consists of up to 10 rules, where each
rule specifies the IP addresses and services that are allowed by the print server and device. To add a rule, click ‘Add
Rule’. This setting runs a wizard that will help you to configure each rule.
