Hello,
I have a Cisco 1841-SEC/K9 and I need it to connect with my LAN and share Internet with it. My Internet connection is ADSL and it provides 1 valid IP Address but it´s dynamic. So i configured the outside interface to get the IP from the DHCP in the ISP. I configured Dynamic NAT, the static route, and the ACL for my Inside Interface, but i still don´t get any Internet Connection. Also my ip name-server is wrong in this configuration, it says that is 200.44.32.13 and it should be 200.44.32.12 but when i try to erase it and add a new one it doesn't change it. Could you help me? Here´s the config:
