B. Directions of Traffic Through a Firewall

The table below describes the port numbers of the ports that are used by SSO programs and NNMi and the directions of traffic through the firewall.

Note that, as the port number of the communication source, a port number not being used by the source host is assigned.

#1

Default value.

#2

This direction of traffic through the firewall applies to the case in which a connection is established from the local host to SSO on a remote host through window operations or by executing a command. This direction of traffic also applies to the case in which a connection is established from the SSO console to SSO.

#3

If the SNMP agent is the ESA for Red Hat Enterprise Linux, the default port number is 22161.

#4

This direction of traffic through the firewall applies to the case in which an APM event is reported as an SNMP trap in a basic system configuration.

#5

This direction of traffic through the firewall applies to the case in which an APM event is reported as an SNMP trap in a distributed system configuration.

#6

This direction of traffic through the firewall applies to the case in which a Web browser is used to access SSO.

#7

This port number is that of the NNM Web server port of NNMi defined in the NNM information definition file.

#8

This direction of traffic through the firewall applies to the case in which an event is reported to the SNMP manager (for example, NNM) on a remote host according to definitions in the event destination definition file.
