Configure multiple interfaces to work simultaneously:
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# NAT
allow-hotplug eth0
iface eth0 inet dhcp
# Internal
allow-hotplug eth1
iface eth1 inet dhcp
# Host-only
allow-hotplug eth2
iface eth2 inet dhcp
# The loopback network interface
auto lo
iface lo inet loopback
$ ifup eth0
$ ifup eth1
$ ifup eth2
Route inner traffic to eth0 (lan), Internet to wlan0 (wan):

Add a static route to wrap all traffic into the VPN gateway. To achieve that specify VPN interface id in hexadecimal (
0x10 in this example) and set higher priority for this route (i.e., lower metric) than default gateway route has:Cmd > route add 0.0.0.0 mask 0.0.0.0 192.168.100.1 metric 7 if 0x10
Cmd > route print -4

Cmd > route add 0.0.0.0 mask 0.0.0.0 192.168.100.1
