Hello, I want to setup my PVE server with one NIC for administration and one for internet access. What do I need to configure to segregate admin traffic from data traffic.
My admin IP when I installed is 192.168.1.10 the network IP for internet is 10.0.10.10, this second IP is connected to my firewall and local LAN. the admin IP I connect to with a small switch. I can't get access to the internet through the second port. What am I missing to be able to access the internet from the node.
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.10/24
gateway 192.168.1.1
bridge-ports eno1
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet static
address 10.0.1.10/24
bridge-ports eno2
bridge-stp off
bridge-fd 0

source /etc/network/interfaces.d/*
 
A simple gateway switch should be enough. Remove the gateway from vmbr0 and add the ip of your firewall to vmbr1 as gateway.
