Configuring Incoming Tunnel Connections

By default, CommCell components accept both secure (HTTPS) and unsecure (HTTP) tunnel connection requests.

You can configure client computers and client computer groups to receive only secure connections. This forces all incoming tunnel connections to use HTTPS by authenticating and setting up HTTPS encryption.

Before You Begin

  • If your clients are separated by a firewall, review the supported firewall types described in Firewall: Overview, then configure the CommCell components as appropriate for your installation.
  • If your clients are not separated by a firewall, configure a one-way firewall just to initiate a tunnel connection to enforce HTTPS transport. Based on the direction in which the connection is initiated, select the appropriate method to configure the firewall from Firewall Using Direct Connections.


  1. From the CommCell Browser, expand Client Computers, right-click the client and then click Properties.

    The Client Computer Properties dialog box appears.

  2. Click Network.

    The Network Properties dialog box appears.

  3. On the Firewall Configuration dialog box, select the Configure Firewall Settings check box and then click Advanced. Click OK to acknowledge the warning and continue.
  4. On the Options tab, select the Force SSL authentication in incoming tunnel connections check box and click OK.
  5. Click OK to save your changes.
