HP Officejet Pro 8000 Enterprise Printer Series - Configure the printer's firewall settings

Firewall features provide network-layer security on both IPv4 and IPv6 networks. The firewall provides simple control of IP addresses that are allowed access.
note:
In addition to firewall protection at the network layer, the printer 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 firewall operation on the printer, you must configure a firewall policy to apply to specified IP traffic. Firewall policy pages are accessed through the EWS and displayed by your Web browser. After a policy is configured, it is not activated until you click Apply in the EWS.

Creating and using firewall rules

Firewall rules allow you to control IP traffic. Use firewall rules to allow or drop IP traffic based on IP addresses and services.
Enter up to ten rules, each rule specifying the host addresses, services, and the action to take for those addresses and services.
This section contains the following topics:
Create a firewall rule
To create a firewall rule, complete the following steps:
  1. Open the embedded Web server.
  2. Click the Settings tab, click Firewall Rules.
  3. Click New, and then follow the onscreen instructions.
Change the priority of firewall rules
To change the priority in which a firewall rule is used, complete the following steps:
  1. Open the embedded Web server.
  2. Click the Settings tab, click Firewall Rules Priority.
  3. Select the priority in which you want the rule to be used from the Rule Precedence list, with 1 having the highest priority and 10 having the lowest priority.
  4. Click Apply.
Change firewall options
To change firewall options for the printer, complete the following steps:
  1. Open the embedded Web server.
  2. Click the Settings tab, click Firewall Options.
  3. Change any settings, and then click Apply.
    note:
    After clicking Apply, the connection to the EWS might be temporarily disrupted for a short period of time. If the IP address was unchanged, the EWS connection will be enabled again. However, if the IP address was changed, use the new IP address to open the EWS.
Reset firewall settings
To reset the firewall settings to the factory defaults, restore the printer’s network settings.
Limitations to rules, templates, and services
When creating firewall rules, note the following limitations to rules, templates, and services.
Item
Limit
Maximum number of rules.
11
Maximum number of Address Templates.
Note the following:
  • All IP Addresses Results in two (2) address template rules. One for all IPv4 addresses, and another for all IPv6 addresses.
  • All non link local IPv6 Results in four (4) address template rules:
    • ::to
      FE7F:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for both local and remote addresses
    • ::to
      FE7F:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for local addresses
    • FE81::to
      FE7F:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for remote addresses
    • FE81::to
      FE7F:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for local addresses
    • ::to
      FE7F:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for remote addresses
    • FE81::to
      FFFF:FFFF:FFFF:FFFF:FFFF:FFFF: FFFF:FFFF for both local and remote addresses
  • All Broadcast/Multicast Addresses Results in four (4) address template rules:
    • 224.0.0.0 to 239.255.255.255 IPv4 local addresses and all IPv4 remote addresses
    • A single IPv4 local address, and all IPv4 remote addresses
    • 255.255.255.255 local address, and all IPv4 remote addresses
    • FF00:: / 8 local IPv6 addresses, and all IPv6 remote addresses
NOTE: To avoid multiple rules for these predefined address templates, you can create custom address templates.
12
Maximum number of user-defined address templates.
5
Maximum number of services you can add to a user-defined service template.
NOTE: The predefined All Services template is not subject to this limitation and includes all services supported by the print server.
64
Maximum number of services you can add to the policy.
For example, if a user-defined service template consists of 64 services, then it is the only service template you can use.
64
Maximum number of service templates in the policy.
10
Maximum number of user-defined custom service templates.
