Good evening.
We have created two nodes on open servers and configured MDPS on them. Full access to the management web interface of the management plane is provided.
After both nodes were combined into a cluster (HA) , access to the web interface disappeared. While troubleshooting, we noticed that when tcpdump was enabled to listen to the management interface on the management LAN, access to the Gaia portal was miraculously restored.
Could you please explain what could be the reason for this behavior? I suspect there is asymmetric routing (the data plane and management plane we have different default routes).
Thanks.
