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.

Given that the two routers allow all connections to pass from either side the simplest thing is to add new IP addresses to the two interfaces of DEV2. We do this so that DEV2 can easily distinguish between packets meant for it, and packets meant to go through:

It seems that you are log-rotating already log-rotated logs.
In your config you use /var/log/upstart/*-server.log.* to select the files to rotate. This expression matches graylog-server.log.1 but no graylog-server.log. So you are rotating the old rotated log files but not the current log file.
