# Users must change the PortalGroup section(s) to match the IP addresses
# for their environment.
# PortalGroup sections define which network portals the iSCSI target
# will use to listen for incoming connections. These are also used to
# determine which targets are accessible over each portal group.
# Up to 1024 portal directives are allowed. These define the network
# portals of the portal group. The user must specify a IP address
# for each network portal, and may optionally specify a port and
# a cpumask. If the port is omitted, 3260 will be used. Cpumask will
# be used to set the processor affinity of the iSCSI connection
# through the portal. If the cpumask is omitted, cpumask will be
# set to all available processors.
# Syntax:
# Portal <Name> <IP address>[:<port>[@<cpumask>]]
