Configuring firewall settings

When the Unable to Access Host message appears, the target firewall is enabled. By default, the target firewall is enabled in Linux.

To recover remote Linux functionality, the target and host firewall must be disabled or reconfigured to allow IP traffic through the ports needed by HP Smart Update Manager to deploy firmware. For a list of the ports that need to be configured in the firewall, see Allowing ports in HP Smart Update Manager.
