I have a device DEV1 which should communicate with device DEV3, however in the middle there is DEV2.
My understanding is that I need to use IP Forwarding in DEV2 and edit route tables on DEV1 and DEV3.
For DEV2 I have enabled IP Forwarding:
-> sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
I can`t set up rest of the things. Could you please help me?
