To configure networking:
Configure the first interface as the management interface:
IP address: 10.0.0.21
Network mask: 255.255.255.0 (or /24)
Default gateway: 10.0.0.1
Configure the second interface as the instance tunnels interface:
IP address: 10.0.1.21
Network mask: 255.255.255.0 (or /24)
The external interface uses a special configuration without an IP address assigned to it. Configure the third interface as the external interface:
Replace
INTERFACE_NAME
with the actual interface name. For example, eth2 or ens256.Edit the
/etc/network/interfaces
file to contain the following:# The external network interface auto
INTERFACE_NAME
ifaceINTERFACE_NAME
inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down
Restart networking:
# service networking stop && service networking start
