Destination IP addresses that don't exist on network.
I have a BGW210 router/modem/switch combo from AT&T. There have several items connected via Wi-fi and one device connected via ethernet. The ethernet connected device is the one in question. This device is a computer that is utilized by my roommate for their job at home. The home network utilizes a standard private IP addressing scheme (i.e. 192.168.x.x). There are no other subnets, switches, or other network devices being used. My issue surrounds log entries relating to this work computer. The work computer (192.168.1.XXX) is logged in the BGW210 device as being the source address and the destination device is logged as being 192.168.2.XXX. There are no other devices identified in the 192.168.2.XXX network. The other part of this issue is that there are multiple instances of logs that are cookie cutter to this, however, they differentiate. Sometimes, the destination source shows 192.168.0.XXX while other times it is logged as 192.168.5.XXX. I am trying to understand what is going on and why data is being logged as transferred between a legitimate device on one network address to another device on a network address that doesn't exist.
