Hi Ruslanas, The tripleo documentation have a decent section[1] on deploying an overcloud with overcloud nodes on a routed network. It shows how to configure the remote networks in undercloud configuration, what addresses the dhcp-relay should forward requests to and how to set the baremetal port's physical network attribute (i.e what maps host A to network A, and host B to network B). -- Harald [1] https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features...

Hi all,
My remote network is a different one: 10.41.94.240/28, just in case :)
Should I add the remote network or subnet to my existing network in undercloud? Or new subnet, which is configured on remote site? if yes, how to specify, that A host should be used on the A network, and B host on the B network. how to add it? fi
I believe FW is all to all. But at this stage, my main concern is that I do not get any info into log in dnsmasq.log
Any thoughts?

Hi all,
Could someone help me, I do not get, I try to boot remote host (behind Firewall). I have dhcp-relay configured. And finally, I see the DHCP request, but nothing else happens... except me crying ;'( "D
DHCP request captured on undercloud vnet5 where dhcp is listening also on eth1, But I am not able to load a remote host. I had a thought, maybe DHCP is generally not working, but one node which is local, I am able to introspect and provide it. completely nothing in /var/log/containers/ironic- inspector/dnsmasq.log
Any suggestions?
My network, which I used and have configured on undercloud host is: 10.120.191.80/28 and IP for DHCP which is configured as dhcp relay is 94.
