En or Dis? Optionally Enabled or Disabled? — this field indicates whether
customers can enable or disable a layer-4 port changing its default port
setting. Valid values are Yes or No.

disabled).

Default Port
State
Default Port State — a port is either open, closed, filtered or N/A.
• Open ports will respond to queries.
• Closed ports may or may not respond to queries and are only listed
when they can be optionally enabled.
• Filtered ports can be open or closed. Filtered UDP ports will not
respond to queries. Filtered TCP will respond to queries, but will not
allow connectivity.
• N/A is used for the egress default port state since these are not
listening ports on the product.
Remote Device Remote Device — this is the remote device that is initiating a connection
request (Ingress Connections) or receiving a connection request (Egress
Connections).
Ext to Branch? External to Branch? — this indicates whether traffic to this layer-4 port is
needed between the branch and other sites, requiring this port to be open
on firewalls, if any, between the branch and the rest of the customer’s
network. Note that this depends on the customer’s deployment. Valid
Values are:
• Yes (meaning typically needed)
• No (meaning not expected to be needed)
• Depends (on customer deployment)
