Yes.  Each of your two interfaces has the same mask (the "Mask:255.255.255.0" 
bit), and because of this they are on different networks.

eth0 can communicate with all machines with addresses 192.168.1.*.
eth1 can communicate with all machines with addresses 192.168.2.*.

To have communication between them (or with other networks), you need to have 
routing information set up appropriately.
