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: and IP for DHCP which is configured as dhcp relay is 94.

output from tcpdump:
