Example Network Configuration: External/Internal IPs, DHCP, Routing, ACL, and NAT

Example: External network IP: 202.100.1.1/24, Gateway: 202.100.1.2.

Internal network IP: 192.168.1.1/24.

Configuration:

[route]dhcp enable

[route] int g0/0/0

[route] int g0/0/0 ip address 192.168.1.1 24

dhcp select interface

dhcp server dns-list 218.85.152.99

int g0/0/1

ip address 202.100.1.1 24

ip route-static 0.0.0.0 0.0.0.0 202.100.1.2

acl 2000

rule permit source 192.168.1.0 0.0.0.255

int g0/0/1

nat outbound 2000

exit

All the above are practical configuration commands.
