    Using SBS2003 SP1 Standard Edition & Exchange 2003 SP2.

    LAN: Server name: serverbox.home.local with LAN IP address 192.168.0.1
    DNS zone in my LAN is home.local

    WAN: External IP address 111.222.333.15 (bogus) from ISP
    DNS name of my WAN connection: bogus.isp.com
    Regular website of ISP: http://www.isp.com with IP 111.222.333.42 (bogus)

    When I am anywhere on the internet, the command “ping bogus.isp.com” results in a working reply from 111.222.333.15.
    The command “ping http://www.isp.com” results in a working reply from 111.222.333.42. This is all fine.

    When I am in the office, the command “ping bogus.isp.com” results in a working reply from 111.222.333.15 and http://www.isp.com returns 111.222.333.42. That’s nice, but I want something different.

    What I want is a different IP address for bogus.isp.com when I am on my LAN.
    The command “ping bogus.isp.com” should result in reply from 192.168.0.1.
    The command “ping http://www.isp.com” should still reply from 111.222.333.42.

    So I tried to add the host bogus.isp.com in the DNS of serverbox.home.local with IP 192.168.0.1. No luck.
    bogus.isp.com is translated to bogus.isp.com.home.local.

    Have tried adding a point (bogus.isp.com.) but the DNS gui refuses that.

    Have added a new primary zone isp.com to my DNS, but then I can’t find http://www.isp.com (and all the other ISP hosts) anymore. Removed this test.

    Who has the working solution here?
