Recently i do a fresh nethserver 7.9 installation on a Proxmox VE. The nethserver is used like gateway and i also have running other modules and services like firewall and atuth proxy and PDC. On my green network i have installed a dhcp service and i have some wired Windows 10 client whos are joing to the domain and use nethserver like dhcp but happend me that if i restart or just suspend or maybe unpluged the wired of the client and after plugin it back again this client dont see the nethserever DHCP not matther that the client have a ip reservation or not in the nethserver dhcp place. When that happend i do and ipconfig on the windows clienyt and all is good showme all the parametter with the rigth configuration like i discribed below but when i do a ping to the nethserver the network is unrecheable but the ping to the nethserver AD ip i get response like to the Proxmox VE.
- I use a proxmox 6 based on debian buster and i already installed a desktop enviroment xfce on it. But i dont think that this have something to do because i test without the desktop enviroment xfce for the proxmox and i get the same result.
- If i do a ping from the nethserver to the client or go to the nethserver diagnostic tab and scan the green network i get response or see the windows client after that the windows client start to get connection again at the moment.
