There are two entries in this table. From my understanding first is used for all outgoing traffic (local address of my modem is 192.168.1.1 ), and part of OS which is responsible for networking just passes packet to modem which send it to ISP etc. But, I am not sure what is second entry for. At first I thought that it is used for incoming traffic but destination address seems wrong since local address of host is 192.168.1.3 according to ifconfig

So, am I wrong about first entry? What is purpose of second one?
