Hi,

I have configured my Cisco ADSL 837 router for PPPoA. I am able to ping both inside and outside the network, even using the FQDN like www.google.com etc and IP address as well. I am also able to telnet one of my remote Cisco router in other city using IP address, But i am not able to access internet. My router is using the Static IP address with Static DNS as well. The ISP has assigned me Default Gateway as well but I have not configured it on Cisco router.

can anybody please guide me how i can access internet and if i am amking any mistake please let me know how i can solve it.


Thanks

I am not a Cisco person but that Default Gateway omission, doesn't seem logical

 

I am posting my running configuration for you people. Please let me know if i am making any mistake in configuration. Thanks

The problem is that your inside hosts are not being nat'ed. You have ip nat inside and outside staements on the correct interfaces, and a suitable nat rule:

ip nat inside source list 1 interface Dialer0 overload

- but you have no access-list 1 which selects what traffic should be nat'ed. Try adding:

access-list 1 permit 10.0.0.0 0.0.0.255 any

You should also add a dialer-list:

dialer-list 1 protocol ip permit

As well, you should be careful when posting configs, you have listed your password and ip address. I would immediately change the password! Also, you can improve the security of the router, e.g. ios firewall and an external access-list, and other things.
