Using NAT with DHCP on Wan side

Answered Question
Feb 11th, 2010

Hey guys, I'm currently enrolled in the cisco networking academy through school, and I will be soon purchasing a Cisco 2600 series router to practice with at home.

I was doing some configuring on packet tracer, and was wondering if it is possible to setup NAT to provide internet access for multiple PCs on a cable internet connection (DHCP).

ip nat pool pool_name start_ip end_ip netmask a.b.c.d

From what I understand on this command is that you can only translate LAN addresses to a static WAN address.

Any help would be greatly appreciated.

I have this problem too.

Hello Steven,

you can use something like

ip nat source inside list 11 interface wan_interface_name overload

this is the typical setup the key is to use the interface name as a reference

Hope to help

Yeah I actually JUST figured that out, while I was researching it a bit more.

Ended up using

int fa0/1

ip nat inside

int fa0/0

ip nat outside

ip nat inside source list 7 interface fa0/0 overload

access-list 7 permit 10.10.0.1 0.0.0.254

my addresses are now translating in packet tracer ^_^

Thanks.
