Cisco 877 - routing issue?

 

Hi all,

 

I've got a problem with a config on my 877 router, and I just can't find the solution.

issues:

1. Using the config below, I can connect to the internet fine, and ping internet IP addresses from the router (but I can't resolve names.. e.g. ping google.co.uk )

2. My laptop will connect to the router and get an IP address from the DHCP pool. I can telnet / ping the router without a problem, but I can't ping anything on the internet ( name or IP ) I'm, guessing its a routing issue between the Dialler10 and vlan1, but I can't seem to resolve it.

Any help would be most appreciated, as its driving me up the wall stairring at the config.

Many thanks in advance.

Dave

you need the NAT interface

you need the NAT interface overload statement....

Aplly the config:

 

ip dhcp excluded-address 192.168.3.254

Access-list 12 permit 192.168.3.0 0.0.0.255

Ip nat inside source list 12 interface dialer10 overload
