5IPsec/Firewall configuration (V. 45.xx.nn.xx)

(Full-featured print servers only) IPsec/Firewall features provide network-layer security on both IPv4 and IPv6 networks. The Firewall provides simple control of IP addresses that are allowed access. Internet protocol security (IPsec, RFC 2401) provides the additional security benefits of authentication and encryption,

IPsec configuration is relatively complex. However, because IPsec provides security at the network layer and can be relatively independent of application layers, the opportunity for secure host-to-host communications over a widespread network, such as the Internet, is greatly enhanced.

●If IPsec is supported, you can control IP traffic using both Firewall and IPsec protection.

●If IPsec is not supported, you can control IP traffic using Firewall protection.

NOTE: In addition to Firewall and IPsec protection at the network layer, the print server also supports an SNMPv3 agent at the application layer for management application security, and open secure sockets layer (SSL) standards at the transport layer for secure client-server applications, such as client-server authentication or HTTPS Web browsing.

For IPsec/Firewall operation on the print server, you must configure an IPsec/Firewall policy to apply to specified IP traffic. IPsec and Firewall policy pages are accessed through the HP Embedded Web Server and displayed by your Web browser. Typical IPsec and Firewall policy pages are shown below.

NOTE: To ensure communications with an HP Jetdirect print server configured with an IPsec policy, ensure that computer systems communicating with the print server are properly configured. IPsec policies configured on the print server and computer systems must be compatible. Otherwise, connections will fail.

After a policy is configured, it is not activated until you click Apply button.
