Configuring static IP

[danwald10]

Hello!

I am trying to assign static IPs to two pines and be able for them to ping each other(for future ssh).

I have edited /etc/network/interfaces:

Code:

interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
# source-directory /etc/network/interfaces.d
# commented out, so it doesnt conflict with this config

# Disable wlan1 by default (8723bs has two intefaces)
iface wlan1 inet manual

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 4.2.2.1 4.2.2.2 8.8.8.8

similarly the second one with the IP: 192.168.1.101, left everything else the same.

I also set managed=true /etc/NetworkManager/NetworkManager.conf so it uses the data from /etc/network/interfaces

Code:

[main]
plugins=ifupdown,keyfile,ofono
dns=dnsmasq

[ifupdown]
managed=true

After a restart I can see in the network manager that both of them are corretly configured, but if I try to ping them with(from 192.168.1.101):
ping 192.168.1.100
it doesnt work.

but if I try to ping the address of my switch: 192.168.1.1, it works on both of them.

The switch in configured with the same gateway and IP: 192.168.1.1
I used longsleeps 10160528 desktop build.
I also cant go on the internet, which is connected to the switch. But between them is a router. Do I have to find out the IP of the router and set it the gateway address of the switch?

I tried using diffrent addresses for the switch(like 192.168.1.2) and use this as a gateway address in /etc/network/interfaces, but still nothing.

Any suggestions on how to make this work?
Also keep in mind, that I am a linux beginner and never did any real networking, so if you can, answer with detailed explanations and forgive my noobism.
