Hi, i just test the connection on Port GiEth0/1/1 (VLAN10)

Client is a PC, setting: DHCP. Client receive the proper IP 10.0.10.100 from ClientPrinter Pool, with the right gateway (10.0.10.2, and DNS 8.8.8.8)

But no internet on this PC. Ping the gateway works.

I changed the config to the suggested, without success. There is only internet from Cisco CLI  

 

sorry missed the point on 

 

interface Dialer1
 ip nat outside
