Hi
I have netgear modem i want to connet Cisco Router 2811 for natting. So what are the commands to configure the router. I got all the details for ADSl connection which provided by the ISP. i need step by step commands so that i can configure the router for natting purpose.
I want to bring another 2 computers on the network through the cisco 2811 router.
Thanks

1. create your pool
ip nat pool
2. create access-list taht will allow your private address to be nat'ed
access-list 1 permit 192.168.1.0 0.0.0.255
3. do static translation if any needed
ip nat inside source static
4.inform your interfaces
int e0
ip nat inside
int s0
ip nat outside
5-start your nat
ip nat inside source list 1 pool
overload is optional if you have only one public ip address
i hope that helped...

Hi,
To make ur router do the isp authentication
Step1:
!
Interface serial #connection to modem
description ADSL Internet connection
no ip address
duplex auto
speed auto
pppoe enable
pppoe-client dial-pool-number 1
no cdp enable
!
Step2
interface Dialer1
ip address dhcp # if u have static ip from ISP configure it#
ip nat outside
no ip redirects
no ip unreachables
no ip proxy-arp
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication chap pap callin
ppp chap hostname #####
ppp chap password 7 #######
!
Step 3: Nat and default route
(config)#ip route 0.0.0.0 0.0.0.0 dialer 1
(config)#access-list 10 permit 192.168.0.0 0.0.0.255
(config)#ip nat inside source list 10 interface dialer1 overload
u already have the ip nat inside command on
ur int e0
Hope this helps
Thanks

Abdul,
'pppoe enable' is an interface command, not a global config command.
For further info on PPPoE implementation please read
