IPsec/Firewall Policy

(Full-featured HP Jetdirect print servers only) The Firewall and Internet Protocol security (IPsec) features provide

network-layer security on both IPv4 and IPv6 networks. The Firewall provides simple control of which IP

addresses are allowed access. IPsec (RFC 2401) provides the additional security benets of authentication and

encryption.

IPsec conguration is relatively complex. However, because IPsec provides security at the network layer and can

be relatively independent of the 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 trac by using both Firewall and IPsec protection.

●

If IPsec is not supported, you can control IP trac by using only Firewall protection.

NOTE: In addition to Firewall and IPsec protection at the network layer, the HP Jetdirect print server also

supports the following:

●

An SNMPv3 agent at the application layer for management application security

●

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 HP Jetdirect print server, use this option to congure an IPsec/Firewall policy

that is applied to specied IP trac. For more information about conguring IPsec/Firewall policies and the

specic settings, see the HP Jetdirect Print Servers Administrator’s Guide.

NOTE: To ensure communications with an HP Jetdirect print server that is congured with an IPsec policy,

computer systems that communicate with the print server must be properly congured. IPsec policies that are

congured on the print server and computer systems must be compatible. Otherwise, connections fail.
