I'm trying to connect to my OWA externally. I'm currently running MS Exchange Server 2003 along side MS SBS 2003. I can access OWA perfectly on site but when trying to access via the internet http://MyPublicStaticIp/exchange I receive a page not found. My server is connected to the internet via a Draytek 2800 series ADSL Router and I have VPN set up via the router which I can access with no problems using my Public static IP. I am not running ISA at the moment but as I understand that although this adds extra security it is not a necessity. I am also not running front and back end exchange servers. Any help to resolve this issue would be much appreciated.
Software/Hardware used: SBS 2003; Exchange Server 2003
