Example Network Configuration: External/Internal IPs, DHCP, Routing, ACL, and NAT
This article provides a step‑by‑step network configuration example showing how to set external and internal IP addresses, enable DHCP, define static routes, create ACL rules, and configure NAT outbound translation on a router.
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.
