Troubleshooting the connection between Content Gateway and Forcepoint DLP
If Content Gateway cannot register with Forcepoint DLP components (an error appears in the Content Gateway manager), be sure that a ping from the proxy machine to the Forcepoint management server succeeds.
If the ping fails, use the ipconfig command on the management server machine to verify its IP address.
*
If the proxy is on a Forcepoint appliance, try pinging the IPv4 address of the appliance's C interface from the management server.
*
If the proxy is not on an appliance, try pinging the IPv4 address of the Content Gateway host system eth0 network interface from the management server.
The registration process requires that Content Gateway is reachable on eth0. After registration, the IP address may move to another network interface on the system, but that IP address must remain available while the modules are being registered.
If Content Gateway is deployed as a transparent proxy and the communication interface ("C" on a Forcepoint appliance) is subject to transparent routing, the registration process was likely intercepted by the transparent routing and prevented from completing. Ensure that traffic to and from the communication interface is not subject to transparent routing.
If registration still fails, make sure that neither the proxy machine nor the management server has a machine name with a hyphen in it. This has been known to cause registration problems.
And make sure the Content Gateway machine has a fully qualified domain name (FQDN) that is unique in the network. Hostname alone is not sufficient to register the proxy with the management server.
