    At work I access the internet through a Cisco ASA 5510.

    We also have a webserver at the same subnet as myself, that is visible
    from the outside (the internet). However it is not visible from the
    inside. I have to use some internal 192.168.1.* address to access it
    from the inside. But all our DNS addresses points to our external IP
    visible only from the outside.

    Is is possible to configure an Cisco ASA 5510 to access the outside
    address from the inside? Our network department has not been able to
    make it work.

    Thanks in advance

  3. put your servers accessable from internet on a DMZ (Which I hope you have
    allready done!) and give this DMZ public IP's
    Then your problems are gone, but access and DNS.
