Cisco 837 Connection to ISP

Level 1

I am trying to connect Cisco 837 router to Tiscali Network for home networking. Below is the router's current config but my laptop can not connect to internet or ping Tiscali DNS. Carrier Detector (CD) light is showing and laptop has static ip address which can PING Router/Default Gateway. Below the copy of the current config is the Tiscali settings from their website, can anyone tell me how to input these Tiscali settings into my current config please?

Hello Keith,

try and add the following to your configuration:

interface Ethernet0

description Local LAN

no shutdown

ip address 192.168.1.2 255.255.255.0

no keepalive

no cdp enable

--> ip nat inside

hold-queue 100 out

interface Dialer1

no shutdown

ip address negotiated

encapsulation ppp

no ip split-horizon

dialer pool 1

--> dialer-group 1

no cdp enable

--> ip nat outside

ppp chap hostname xxxxxxxxxx@tiscali.co.uk

ppp chap password xxxxxxx

!

--> ip nat inside source list 1 interface Dialer 1 overload

--> access-list 1 permit 192.168.1.0

--> dialer-list 1 protocol ip permit

Check if that makes a difference...

Regards,

GP

Hello GP,

Apologies for not knowing your firstname. I have amended the config to include the command lines you suggested above but still I can not ping the DNS address, hence can not get on to the internet. I believe it has something to do with the Tiscali settings which are:

Virtual Circuit Identifier - VCI 38

Virtual Path Identifier - VPI 0

Encapsulation Mode VCMux

Authentication Type CHAP

Protocol RFC 2364:

PPP over ATM (PPPoA)

Modulation Type G.DMT or Auto

Tiscali Primary DNS Server 212.74.112.66

Tiscali Secondary DNS Server 212.74.112.67

Please can anyone help???

Hello Keith,

does your dialer interface get a public IP address at all ?

Regards,

GP

Hi GP,

The router does get a public address and the laptop gets a private address which can ping the public but can not ping the DNS addresses.

Regards

Keith

Hello Keith,

sorry for asking lots of questions, but when you say you can ping the public address, does that mean that you can ping the public address assigned to your interface, or can you ping an address on the Internet, such as 193.194.158.86 ? I am just trying to find out if your NAT works properly...

Regards,

GP

Hi GP,

I have tried to ping the public address you suggested with no look it just request times out like when trying to ping Tiscali DNS. I can only ping the routers public & private addresses nothing else on the network.

Warm Regards

Keith
