Hi All,

I am having issues getting to the internet from the PC. It's currently connected to the cisco 877w via FE0.

The PC is able to grab the correct IP address. Even when I input the dns [8.8.8.8], I am still not able to access the internet.

Attached is the config -

Can you ping 8.8.8.8 from your router? If so, all you'll need is to configure nat on the router:

access-list 100 permit ip 192.168.1.0 0.0.0.255 any

ip nat inside source list 100 interf dialer0 overload

int vlan 1

ip nat inside

int dial0

ip nat outside

Thanks so much for the help! All is working fine now. So it's all about the ACLs that is causing the issue. cheers.

One more question - can someone please teach me how to configure the wireless module of this 877w?

Can you souce a ping from your vlan1 interface to 8.8.8.8?

For Example: ping 8.8.8.8 source 192.168.1.254

Also can you post the results of a traceroute to 8.8.8.8 from this PC?

And my last question, is your Internet Service currently up?

@John - thanks but I got it all sorted out.

cheers

If you can assist with the wireless, it would be very much appreciated!

Can you start a new post about your wireless issue?

Thanks!
John
