Hi Aron,<br>
<br>
Thank you for your reply.<br>
<br>
We deploy one (quantum) subnet as a DMZ network and the other (quantum) subnet<br>
as a non-DMZ network.<br>
They are routed to the network node where quantum services (dhcp, l3, linuxbridge)<br>
are running.<br>
They can talk each other through network node, now.<br>
<br>
However, we do not want to the network node to route the traffic between them directly.<br>
Instead we want them to be routed to different (external) routers such that<br>
we can apply filtering/firewall/etc. on the traffic from DMZ network.<br>
<br>
Do you think is it possible using two l3-agents or any other way?<br>
Currently, I manually set up routings for those two subnets.<br>
<br>
Thanks,<br>
David<br>
