What are the limitations of packet filtering?
What will be an ideal response?
Filtering does not hide the IP addresses of the hosts that are on the network inside the filter. The IP addresses are contained in the outbound traffic, which makes it easy for attackers to target individual hosts behind the filter to attack them. Filters also don't check to make sure the protocols inside packets are legitimate. Packet filtering can limit addresses based only on the source IP address listed in the packet's header, and thus it does not protect against IP spoofing. For these reasons, firewalls that perform only packet filtering do not provide adequate network protection.
