NethServer Version: NethServer release 7.3.1611
I had gotten a new modem (Netgear CM500) so I had to setup a gateway (my last modem was a combo) Once I was done fiddling with my Nethserver install that I was using for mail and web I had gotten DHCP and some port forwards in. I had a few issues of loosing connection so I didn’t think much of it the first few times so I restarted the Nethserver virtual machine. I found out later on that the internet connection was dropping exactly every hour.
I’m running Nethserver on Proxmox on a Dell PowerEdge R610
