Step and configure IP Connectivity DHCP and PAT

To step and configure IP connectivity DHCP and PAT, follow these steps:

Configure IP addresses on the interfaces of the router using the ip address command. For example:

Router(config)# interface gigabitethernet0/0

Router(config-if)# ip address 192.168.1.1 255.255.255.0

Configure the default gateway using the ip default-gateway command. For example:

Router(config)# ip default-gateway 192.168.1.254

Configure the DHCP server using the ip dhcp pool command. For example:

Router(config)# ip dhcp pool LAN

Router(dhcp-config)# network 192.168.1.0 255.255.255.0

Router(dhcp-config)# default-router 192.168.1.1

Router(dhcp-config)# dns-server 8.8.8.8

Configure NAT using the ip nat inside and ip nat outside commands on the appropriate interfaces. For example:

Router(config)# interface gigabitethernet0/0

Router(config-if)# ip nat outside

Router(config)# interface gigabitethernet0/1

Router(config-if)# ip nat inside

Configure PAT using the ip nat inside source list and interface commands. For example:

Router(config)# access-list 1 permit 192.168.1.0 0.0.0.255

Router(config)# ip nat inside source list 1 interface gigabitethernet0/0 overload

These steps configure IP connectivity using DHCP for automatic IP address assignment and PAT for Internet access.
