- You will need to configure your D-Link firewall for port forwarding. Make sure that it forwards HTTP (port 80) and/or HTTPS (port 443) packets to the internal IP address of the Exchange server. Use either HTTP or HTTPS depending on your security requirements.
- Make sure that your users have an appropriate URL to use for Outlook Web Access. You can use a fully qualified domain name (FQDN) such as https://mail.yourdomain.com/exchange, or even an IP-based URL such as https://220.127.116.11/exchange. If you use the former, make certain that mail.yourdomain.com resolves to the appropriate IP address, which is 18.104.22.168 in my example.
- Look at the Exchweb, Exchange and Public virtual directories in Internet Information Services (IIS) and make certain that you don't have any IP address restrictions that would prevent authorized users from accessing the system.
