HP 630n HP Jetdirect Print Servers - Administrator's Guide - Page 101

CAUTION: You can lose communication with the HP Jetdirect print server if your system is not properly specified in the list, or access via HTTP is disabled. To use the access control list as a security feature, see Security features (V.38.xx) on page 113. Specify host systems by their IPv4 address or network number. If the network contains subnets, you can use an address mask to identify whether the IP address entry designates an individual host system or a group of host systems. Examples: IP Address 192.0.0.0 192.1.0.0 192.168.1.2 Mask 255.0.0.0 255.1.0.0 Description Allow all hosts with network number 192. Allow all hosts on network 192, subnet 1. Allow the host with IP address 192.168.1.2. The mask 255.255.255.255 is assumed and is not required. To add an entry to the access control list, specify a host using the IP Address and Mask fields, select the Save check box, and then click Apply. To delete an entry from the list, clear the Save check box for that entry, and then click Apply. To clear the entire access control list, clear all Save check boxes, and then click Apply. Mgmt. Protocols Use this item to access the management communications and other protocols that affect security. Web Mgmt. Use this tab to manage communications with the embedded Web server from Web browsers. Secure, encrypted Web-based communication is provided through the HTTPS protocol. If configured to require HTTPS, the embedded Web server routes HTTPS communications through port 443, the well known port for HTTPS traffic. Although ports 80, 280, or 631 continue for IPP use, other non-secure communications, such as HTTP, are redirected to HTTPS. Redirection of your browser to use HTTPS can be transparent depending on your browser's capabilities. NOTE: IPP is not supported on value-based print servers. By factory default, HP Jetdirect print servers and printers with IPsec support require HTTPS. Although not recommended, you can allow non-secure HTTPS and HTTP communications by clearing the Encrypt All Web Communication check box. To support the use of HTTPS communications, you must install an HP Jetdirect certificate. A factory default, self-signed certificate is installed for initial use. Click the Configure button to update the installed certificate, or to install a new one. For more information, see Configure certificates on page 88. The minimum encryption strength allowed must be specified when using an HP Jetdirect certificate. Select Low (default), Medium, or High encryption strength. For example, select Low to allow use of medium or high encryption levels. Select High to use only high encryption levels. ENWW Networking tab 91
