host disconnected vs firewall

Hello all,

This week-end, our network engineer has changed a firewall.

Since, I have 2 hosts that are in state "disconnected" in vcenter.

I'm not able to connect them using right click on the host and connect.

I have remove 1 host and add it to vcenter and it is working.

So I suspect some arp table or route table that have changed but I'm not able to find them ( I have used, route, traceroute, route -n, esxcli network ip neighbor list ).

What are the steps vcenter does when it had an ESX host ? I need to understand what happen exactly.

Thanks in advance for helping
