Question:
What is a disadvantage when both sides of a communication use PAT?
- End-to-end IPv4 traceability is lost.
- The flexibility of connections to the Internet is reduced.
- The security of the communication is negatively impacted.
- Host IPv4 addressing is complicated.
Explanation: With the use of NAT, especially PAT, end-to-end traceability is lost. This is because the host IP address in the packets during a communication is translated when it leaves and enters the network. With the use of NAT/PAT, both the flexibility of connections to the Internet and security are actually enhanced. Host IPv4 addressing is provided by DHCP and not related to NAT/PAT.
