Specifically, look at neutron security-group-rule-create:

usage: neutron security-group-rule-create [-h] [-f {shell,table}] [-c
                                          [--variable VARIABLE]
                                          [--prefix PREFIX]
                                          [--request-format {json,xml}]
                                          [--tenant-id TENANT_ID]
                                          [--direction {ingress,egress}]
                                          [--ethertype ETHERTYPE]
                                          [--protocol PROTOCOL]
                                          [--port-range-min PORT_RANGE_MIN]
                                          [--port-range-max PORT_RANGE_MAX]
                                          [--remote-group-id REMOTE_GROUP]

The --direction option is what you're looking for. You may need to remove
a default egress rule... I think by default it allows everything.
