Using IPADM set-prop command, set the property for ephemral ports

# ipadm set-prop -p smallest_anon_port=9000 tcp
# ipadm set-prop -p smallest_anon_port=9000 udp
# ipadm set-prop -p largest_anon_port=65500 tcp
# ipadm set-prop -p largest_anon_port=65500 udp

Configuration is permanent.

# init 6
# /usr/sbin/ndd /dev/tcp tcp_smallest_anon_port tcp_largest_anon_port
9000
65500
