World of Computer Networking Your CCNA start - Static Port Address Translation (PAT)

The video tutorial explains the concept of Network Address Translation (NAT), focusing on static Port Address Translation (PAT). It covers how NAT provides security by allowing many local IPs to be translated to a single public IP, and how static PAT can be used to allow remote access to specific services on a private network. The tutorial also discusses configuring static PAT, using dynamic PAT for outgoing connections, and implementing additional security measures like access lists. Advanced techniques such as port modification and traffic forwarding are also covered, followed by a practice activity to verify NAT settings.

What is the primary function of many-to-one NAT?

• To translate multiple local IPs to a single external IP

• To allow multiple external IPs to connect to a single internal IP

• To block all outbound connections from a private network

• To provide direct access to internal servers from the internet

Why might static PAT be preferred over one-to-one static NAT?

• It uses fewer public IP addresses

• It allows for dynamic port allocation

• It is easier to configure

• It provides better encryption

Which protocol and port does HTTPS use in static PAT?

• UDP, port 53

• UDP, port 80

• TCP, port 443

• TCP, port 22

What is a key requirement when setting up static PAT on a router?

• Static mappings must be manually configured

• The router must have multiple public IPs

• All ports must be open to the internet

• The router must automatically detect server ports

How can additional security be provided when using static PAT?

• By enabling all ports for external access

• By disabling all inbound connections

• By using dynamic NAT instead

• By setting up access lists on the router

What happens to the destination port in static PAT when traffic is forwarded?

• It remains unchanged

• It is replaced with a random port

• It is replaced with the internal server's port

• It is blocked by the router

What is the purpose of using different ports in static PAT translations?

• To increase the speed of data transfer

• To confuse potential attackers

• To reduce the number of required public IPs

• To allow multiple services on the same server
