Description of problem:
When port forwarding using fip is enable only for some ports. Fip is answering to ping.

Version-Release number of selected component (if applicable):

How reproducible:
execute test case:
(overcloud) [stack@undercloud-0 tempest_17.1]$ tempest run -r "test_port_forwarding_editing_and_deleting_tcp_rule"

with pdb breakpoint:
neutron_tempest_plugin/scenario/test_port_forwardings.py:
...
168
169 # Check connectivity with the new parameters
170 server[0]['port_forwarding_tcp']['external_port'] = test_ext_port
171 import sys; sys.stdin = open('/dev/tty'); import pdb; pdb.set_trace();
172 -> utils.wait_until_true(
173 fip_pf_connectivity,
174 exception=RuntimeError(
175 "Connection to the server

through "
...

check fip ip used:

(Pdb) p server[0]['id']
'f00332c4-7083-4f23-9e5f-647112becf39'
(Pdb) p server[0]['port_forwarding_tcp']['floatingip_ip']

• • • KeyError: 'floatingip_ip'
      (Pdb) p server[0]['port_forwarding_tcp']['floatingip']
    • KeyError: 'floatingip'
      (Pdb) pp server[0]['port_forwarding_tcp'] {'client': <neutron_tempest_plugin.services.network.json.network_client.NetworkClientJSON object at 0x7efdfc0fcc10>, 'description': '', 'external_port': 3333, 'floatingip_id': '6b625fce-f3fe-46cc-b4ee-5e4448cde05a', 'id': '1a3160d0-2cfe-44d1-ad8e-c42c79d342f3', 'internal_ip_address': '10.100.0.26', 'internal_port': 22, 'internal_port_id': 'c5395e34-27f6-46c3-b1c3-8f582bc4b101', 'protocol': 'tcp'}

and try ping from the undercloud:

(overcloud) [stack@undercloud-0 ~]$ ping 10.218.0.185
