I would like to set up my Raspberry Pi as static IP device, which communicates over Ethernet (through an IP like 192.168.20.X), and at the same time it should be connected to the internet through WLAN (192.168.1.1). However when I allow 'auto eth0' then it does not configure the wlan0. I would like both of them to work. My current configuration is given below:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.20.40
netmask 255.255.255.0
network 192.168.20.1
gateway 192.168.20.1
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
What am I missing? Any help would be appreciated. Thanks in advance.
