icehouse L3 agent support multiple external networks (?)

[Vasilios Tzanoudakis]

Enviroment has been setup on virtualbox with ISO: fuel-community-5.1.1-92-2014-11-08_05-26-47.iso

Ubuntu + GRE + CEPH
1 Controller Node
1 Compute Node

Created a new internal network 192.168.2.0/24
Created a new external network 172.16.1.0/24 (tried also with provider:network_type=local and provider:network_type=gre) and subnet's gateway set to 172.16.1.1

Created a new Router.
Added internal network port
set gateway from subnet 172.16.1.0/24 and got IP 172.16.1.3 on Router's port.

set to l3_agent.ini
==========
gateway_external_network_id =
external_network_bridge =

Controller node rebooted just to be safe. Also all neutron services restarted and ensured that they are all up.

Created VM on network 192.168.2.0/24
VM got IP 192.168.2.11
VM Can ping router address 192.168.2.1
VM Can ping router external address 172.16.1.3

>>>> The issue: <<<<<<
=========================================
VM CANNOT ping 172.16.1.1 or any other ip over the external network.

This happens also with the preconfigured subnet 172.16.0.0/24 with the same example.

Note:
=============================
Controller Node can ping 172.16.1.1
