Unable to reach internet from proxmox host machine

[chenfw]

Proxmox host machine can't get internet connection, but virtual machine can. ssh has no problem.
Here is `/etc/network/interfaces`

auto lo
iface lo inet loopback

iface enp30s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.0.102
netmask 255.255.255.0
gateway 192.168.0.1
bridge-ports enp30s0
bridge-stp off
bridge-fd 0

Can you ping the gateway? Can you ping an outside IP address?

If yes, do you have the correct DNS servers set?
