HP Matrix Operating Environment 7.2 Update 1 Infrastructure Orchestration User Guide

default cloud firewall blocks all inbound traffic. To allow inbound traffic, you must create one or
more rules on this page that describe that traffic.
The Optional setting makes the template flexible for use with different cloud software images when
using the Custom Attributes feature to customize the operating system at service creation time. For
more information, see “Customizing template attributes when a service is created” (page 128).
A firewall is created as part of the Create Service operation and is uniquely associated with a
single cloud server group within a service. An IO user can only change the rules for the firewalls
associated with services that they own.
Configuring a firewall
1. Select either Required or Optional according to the requirements of your provider.
2. Complete the following steps to set up a firewall rule:
a. Select the Protocol (TCP, UDP, ICMP) for which the firewall rule applies.
b. Enter a Start Port (0–65535) and End Port (0–65535) to specify the port range to which
the rule applies.
NOTE: When the Protocol is set to ICMP, the Start Port and End Port fields are replaced
by Type and Code fields.
c. In IP Sources, enter a comma-separated list of sources of the connections to allow.
Use CIDR notation, which is the IP address followed by the slash (/) character and the
routing prefix size expressed as a decimal number. For example, 127.0.0.1/24.
