Configuring the TCP ports in Content Gateway Manager

For explicit proxy deployments, customers need to tunnel a port range for websocket traffic from the on-premises proxy to Forcepoint RBI.

Note: For transparent proxy deployments, the websocket traffic goes directly to the Internet and does not need to be tunneled. If you are using a transparent proxy, you do not need to tunnel the port range provided below.

Steps

  1. Sign in to the Content Gateway Manager.
  2. Go to Configure > Protocols > HTTP.
  3. On the General tab, add the following port information to the HTTPS ports field: 443.
  4. Click Apply.

Next steps

For both explicit proxy and transparent proxy deployments, update your firewall rules to allow port 443.
