Hello, im new here, and i recently bought a second-hand DL360 G7 and setup Proxmox into it. At the time all things went normal and the ip could go thru firewall and get output to the internet, After about 5hr it suddenly stopped and it couldn't get output to the internet, even cannot ping 8.8.8.8.
Also new into like these rack server's, does it needed to plug all 4 internet cable to work or something else?
here is /etc/network/interfaces
auto lo
iface lo inet loopback
iface enp3s0f0 inet manual
iface enp3s0f1 inet manual
iface enp4s0f0 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.1.200/24
gateway 192.168.1.254
bridge-ports enp3s0f0
bridge-stp off
bridge-fd 0

Really need someone to help me to solve this problem, tysm.
