Problem with EVE-NG Pro external connection

[loydfolse]

Hello,

I recently got EVE-NG Pro for our company. At first, everything was ok but now we have some issues.

Consider this scenario:

I have 3 Debian and 1 Network(management_cloud). All nodes are connected to the Management(cloud0) network and have IPs from the same network as the EVE-NG machine.

When I want to connect to these machines from my computer (with ssh), sometimes everything works properly but sometimes it doesn't. Each time this issue was solved differently, one time by sending ping packets from Debian machines, one time by restarting Debian machines, and if the problem was not solved yet, restarting the EVE-NG machine sometimes solved the problem.

Sometimes at first, the ssh connection worked but after some time the ssh session suddenly gets closed, and then, when I ping that machine, it doesn't respond.
How can I solve this problem?

First check what MAC addresses have your Debian machines connected to cloud ! They should not be same, maybe MAC collision can happen if MAC are same
