DHCP + NAT (PAT) Configuration | CCNA Lab Step-by-Step
In this lab, I configure DHCP and NAT (PAT) on a Cisco router to allow internal devices to automatically receive IP addresses and communicate with external networks.
This is a hands-on CCNA-level lab focused on real-world networking concepts including:
DHCP configuration for automatic IP addressing
NAT (PAT) configuration for internet access
Inside vs Outside interfaces
Verifying NAT translations and DHCP bindings
This lab demonstrates how internal (private) IP addresses are translated into a public IP address using Port Address Translation (PAT), allowing multiple devices to share a single public IP.
Commands covered:
ip dhcp pool
default-router / dns-server
access-list configuration
ip nat inside / outside
ip nat inside source list overload
show ip nat translations
show ip dhcp binding
This video is part of my journey toward becoming a Network Engineer and building a strong networking portfolio.
