By default, the Threat Management Gateway only responds to requests for the public name entered during the Web Site Publishing Wizard. Because additional URLs can be used for dial-in conferencing or meetings, they must be added to the rule.
1. Right-click the web site publishing rule just created and select Properties.
2. Click the Public Name tab.
3. Use the Add button to enter any simple URLs published for dial-in conferencing or meetings.
4. Click the Apply button to save changes after all names have been added, as shown in Figure 6.9.
