Q1) The *Private* IP address of a computer can change if u have configured ur router to use DHCP. There is also the option of setting a static ip. The WAN IP on the other hand can change and most of the times it is under the control of the ISP unless the ISP has given you a static WAN IP.
Q2) IP filtering is simply a mechanism that decides which types of IP datagrams will be processed normally and which will be discarded. By discarded we mean that the datagram is deleted and completely ignored, as if it had never been received. You can apply many different sorts of criteria to determine which datagrams you wish to filter. IP filtering is a network layer facility.
