Installing a SolidWorks Workgroup PDM Web server and Workgroup PDM Viewer in a perimeter network (DMZ) has firewall implications.

Because Workgroup PDM Viewer clients communicate with the Web server over the HTTP or HTTPS ports, these ports must be open on the Internet Information Server (IIS) system where the Web server is installed.

• For the HTTP protocol, the default port is 80.
• For the HTTPS protocol (SSL), the default port is 443.

The Web Viewer clients themselves do not need firewall exceptions.

You must ensure that the Web server system can reach the Vault server over these default ports:

• 30000 (Data)
• 40000 (Request)

• Network Configuration for Workgroup PDM Viewer in a Perimeter Network
  The network configuration shows a perimeter network server set up on a perimeter subnet and its communication to the internal and external networks.
• Installing and Configuring the Workgroup PDM Web Server and Viewer
  When you set up a Workgroup PDM Web server in a perimeter network, the installation location of the components is important.
