Hi All,
I have a Cisco 888 router that is connected to a 8 port non-cisco switch. I have WAN/DHCP configured on the router and the switch is non smart and programmable..
The issus that none of the client machines can access the Internet.They can take an ip from router but doesn t have internet.I try to ping 8.8.8.8 etc but doesn t work. From within the router console, I am able to ping external domain names, my ISP DNS servers.We have static ip from the ISP
Client machines can ping the Cisco router IP.
I have checked google looking for an answer on why, but I am missing something I just don't know why. Any help would be helpful.
Thanks,
Here is the config

Hello Kubilay,
>> We have static ip from the ISP
if you access the internet using ATM0.1 subinterface you need to change your NAT statement in :
ip nat inside source list 1 interface ATM0.1 overload
interface ATM0.1
ip nat outside
but you would need also a default static route using ATM0.1 instead of dialer0
ip route 0.0.0.0 0.0.0.0 ATM0.1
it is not clear.How do you access the internet?
with PPPoE over ATM on pvc8/35 or by using subinterface ATM0.1?
Hope to help

Hello Kubilay,
thanks for rating, just for information your internet access is via the ATM0.1 subinterface?
Because the changes i have proposed were done under this hyphotesis starting from your note about static IP address from ISP.
Best Regards
Giuseppe

Dear Giuseppe,
yess our internet access is via ATM0.1 subinterface.And i added your suggested ip nat as"ip nat inside source list 101 interface Dialer0 overload".After that everyhthing working fine.

Hello I have got the same router and I am trying to connect it to a non CISCO modem but I don't know how because it is not a standard 800 series configuration configuration.
