Masquerading

In computer networking, the process of network address translation (NAT, also known as network masquerading or IP-masquerading) involves re-writing the source and/or destination addresses of IP packets as they pass through a router or firewall. Most systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address (see gateway). According to specifications, routers should not act in this way, but many network administrators find NAT a convenient technique and use it widely. Nonetheless, NAT can introduce complications in communication between hosts.

Spoofing

In computer networking, the term Internet Protocol address spoofing is the creation of IP packets with a forged (spoofed) source IP address. Since "IP address" is sometimes just referred to as an IP, IP spoofing is another name for this term.
