I have a Raspberry pi Device I want to use the (eth0) ethernet port/Cable to connect to a local network with ip range from 192.168.x.x. And i have a 4G usb dongle which connects to the internet on the eth1 interface. Dongles default Ip is 192.168.1.1(not sure this has anything to do with the problem) and reconfigures to the ip connecting to internet.
current setting - eth0 ip - 192.168.200.200 netmask 255.255.255.0 - eth1 ip - 10.228.171.93 netmask 255.255.255.252
The issue arises when i try to change the netmask of eth0 to 255.255.0.0 to connect to the local network. once i change it, access to internet on the device stops and i am not able to ping to google.com or its ip address.
Required setting - eth0 ip - 192.168.200.200 netmask 255.255.0.0 - eth1 ip - 10.228.171.93 netmask 255.255.255.252
I searched similar issues and tried out a few steps but none of it seems to work. resolv.conf has the following IP.
cat /etc/resolv.conf # Generated by resolvconf nameserver 192.168.1.1
/etc/network/interfaces file is as below

I need both the network interface to work
through eth0 i should be able to ping 192.168.x.x through eth1 i should be able to ping google.com
