How can I setup interfaces file to be able to connect the Raspberry pi to the internet (4g USB modem) and at the same time to a PC via SSH (ethernet).
My interface file look like this (/etc/network/interface):
# interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto lo iface lo inet loopback iface eth0 inet manual 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
/etc/dhcpcd.conf looks as follows:-
interface eth0 static ip_address=10.1.1.30/24 static routers=10.1.1.1 static domain_name_servers=10.1.1.1
I am able to connect via SSH but I lose the internet connection.
