Pharming

Explanation: A pharming attacker tries to send a web site’s traffic to a faux website
controlled by the offender, typically for the aim of collection sensitive data from victims or
putting in malware on their machines. Attacker tend to specialize in making look-alike ecommerce and digital banking websites to reap credentials and payment card data.
Though they share similar goals, pharming uses a special technique from phishing.
“Pharming attacker are targeted on manipulating a system, instead of tricking people into
reaching to a dangerous web site,” explains David Emm, principal security man of science
at Kaspersky. “When either a phishing or pharming attacker is completed by a criminal,
they need a similar driving issue to induce victims onto a corrupt location, however the
mechanisms during which this is often undertaken are completely different.”

The gateway is not routing to a public IP address.

Explanation:
https://en.wikipedia.org/wiki/Private_network
In IP networking, a private network is a computer network that uses private IP address
space. Both the IPv4 and the IPv6 specifications define private IP address ranges. These
addresses are commonly used for local area networks (LANs) in residential, office, and
enterprise environments.
Private network addresses are not allocated to any specific organization. Anyone may use
these addresses without approval from regional or local Internet registries. Private IP
address spaces were originally defined to assist in delaying IPv4 address exhaustion. IP
packets originating from or addressed to a private IP address cannot be routed through the
public Internet.
The Internet Engineering Task Force (IETF) has directed the Internet Assigned Numbers
Authority (IANA) to reserve the following IPv4 address ranges for private networks:
· 10.0.0.0 – 10.255.255.255
· 172.16.0.0 – 172.31.255.255
· 192.168.0.0 – 192.168.255.255
Backbone routers do not allow packets from or to internal IP addresses. That is, intranet
machines, if no measures are taken, are isolated from the Internet. However, several
technologies allow such machines to connect to the Internet.
· Mediation servers like IRC, Usenet, SMTP and Proxy server
· Network address translation (NAT)
· Tunneling protocol
NOTE: So, the problem is just one of these technologies.

Dynamic ARP Inspection (DAI)

Explanation:
Dynamic ARP inspection (DAI) protects switching devices against Address Resolution
Protocol (ARP) packet spoofing (also known as ARP poisoning or ARP cache poisoning).
DAI inspects ARPs on the LAN and uses the information in the DHCP snooping database
on the switch to validate ARP packets and to protect against ARP spoofing. ARP requests
and replies are compared against entries in the DHCP snooping database, and filtering
decisions are made based on the results of those comparisons. When an attacker tries to
use a forged ARP packet to spoof an address, the switch compares the address with
entries in the database. If the media access control (MAC) address or IP address in the
ARP packet does not match a valid entry in the DHCP snooping database, the packet is
dropped.
