When using the Web Server Publishing Wizard, there are some settings unavailable that need to be modified after creating the rule. Because the external web services run on an IIS website using port 4443, the following steps are required to redirect Threat Management Gateway rules to this port instead of 443.
1. Right-click the web site publishing rule just created and select Properties.
2. Click the Bridging tab.
3. In the Redirect requests to SSL port, change the 443 to 4443, as shown in Figure 6.8.
4. Click the Apply button to save changes.
