Multiple firewall settings can be included within a single location. One is defined as the default
setting, with the remaining settings available as options for the user to switch to. Having multiple
settings are useful when a user may normally need certain security restrictions within a network
environment and occasionally needs those restrictions either lifted or increased for a short period of
time, for specific types of networking (i.e., ICMP Broadcasts).
Three firewall settings are included at installation, they are:
All Adaptive - This firewall setting sets all networking ports as stateful (all unsolicited
inbound network traffic is blocked. All outbound network traffic is allowed), ARP and 802.1x
packets are permitted, and all network applications are permitted a network connection, all.
All Open - This firewall setting sets all networking ports as open (all network traffic is
allowed), all packet types are permitted. All network applications are permitted a network
connection
All Closed - This firewall setting closes all networking ports, and restricts all packet types.
A new location will have the single firewall setting, All Open, set as the default. To set a different
firewall setting as the default, right click the desired Firewall Setting and choose Set as Default.

6.3.8 TCP/UDP Ports

Endpoint data is primarily secured by controlling TCP/UDP port activity. This feature allows you to
create a list of TCP/UDP ports which will be uniquely handled in this firewall setting. The lists
contain a collection of ports and port ranges, together with their transport type, which defines the
function of the range.
NOTE: This feature is only available in the ZENworks Endpoint Security Management installation,
and cannot be used for UWS security policies.
To access this control, open the Locations tab, click the "+" symbol next to Firewall Settings, click
the "+" symbol next to the desired Firewall, and click the TCP/UDP Ports icon in the policy tree on
the left.
