  • Regarding NAT

    Dear members,

    I have setup a cisco 2800 series router, configured one interface with IP addresse given by my ISP, another interface to my Local LAN, configured NAT policies. Added Default Route and DNS IP Addresses.

    Connected a Desktop PC to LAN port and configured it and tested the connectivity to internet is OK.

    Now when I was trying to ping any domain of outside world (www.yahoo.com, www.google.com) form my Router the ping failed.

    So please tell me what more configuration required to successfully ping www.yahoo.com from my router. This access I required.

    Thank in advance.

    Can you ping by ip address? If so then you know you have a dns issue. Are you doing any filtering on the router (ACL's, CBAC, Zone Based Firewall?)


    ip name-server 8.8.8.8
    ip name-server 8.8.44


    ip domain-lookup


    show hosts - displays the local routers dns cache.

      Also it would help to post a sanitized config of the router.
