Hi all - I'm currently trying to get something working on my openstack platform, wondering if anyone's come across this before.
On a VLAN tenant network, how can I allow an external device to pick up a dhcp address from neutron's dhcp service (the dhcp service associated with the subnet created in the tenant vlan network)? - I'm using liberty, and have created some vlan networks as admin user, and assigned them to the 'demo' project. - logged in as demo, I've created a dhcp-enabled subnet in one of the vlan networks, and a security group that allows hosts in the same subnet to connect to openstack guests in that subnet. - I've created some openstack guest VMs in the subnet - they came up ok and picked up dhcp ip addresses. I can connect to these guests from an external server on the same VLAN (a server outside of openstack). I can connect to the external server from the openstack guest VMs. All as expected. What I'm trying to do is to get an external (non-openstack) device on the same vlan to pick up a dhcp ip address from the openstack dhcp service for that subnet. Using wireshark I can see the dhcp request packets from my device, on the correct vlan, reaching my neutron network node where the dnsmasq dhcp service is running, but there's never a reply. I've tried putting wide-open ingress rules in the security group, but haven't got it to work yet (I'm not actually sure if the security group has any bearing at the subnet level as per AWS, or if it applies only to guest VMs... looks to me like it just applies to VMs). Anyone know what I need to do? I'll keep at it meantime cheers Iain -- _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
