Just in case, could you open an issue in our jira
, when you have time, with debug logs from
the compute and gateway node while running this ping?

Thanks,

This is a known issue. We have it in the backlog to fix but noone has
gotten to it yet.

Are the gateway nodes virtualized? If so, are you allowing promiscuous mode / 
MAC spoofing?

[openstack-dev] [midonet] ping cannot work from VM to external gateway IP.

2015-12-16 Thread Li Ma 
Hi Midoers,

I have a platform running Midonet 2015 (I think it is the last release
when you switch to 5.0).
I cannot ping from VM to external gateway IP (which is set up at the
physical router side).

VM inter-connectivity is OK.

When I tcpdump packets on the physical interface located in the gateway node,
I just grabbed lots of ARP requests to external gateway IP.

I'm not sure how midonet gateway manages ARP?
Will the ARP be cached on the gateway host?

Can I specify a static ARP record by 'ip command' on gateway node to
solve it quickly (not gracefully)?

(Currently I'm in the business trip that cannot touch the environment.
So, I'd like to get some ideas first and then I can tell my partners
to work on it.)

Thanks a lot,

Re: [openstack-dev] [midonet] ping cannot work from VM to external gateway IP.

2015-12-16 Thread Li Ma 
Updated:

Lots of ARP requests from external physical router to VM are catched
on the physical NIC binded to provider router port.

It seems that external physical router doesn't get answers to these
ARP requests.
