Appendix B: Troubleshooting
Users filtered by remote filtering do not receive block pages
If users with the Remote Filtering Client on their workstations are being
filtered properly, but are not receiving Websense block pages, try the
following:
 If there is a firewall between the Websense Filtering Service machine and
the Remote Filtering Server machine, check that it has been properly
configured, as described in Enabling communication between Remote
Filtering Server and Filtering Service, page 216:
 Make sure the Block Page port (by default, 15871) has been opened
on the firewall. This allows Filtering Service to send block pages to
remote users.
See the documentation for your firewall product if you need information
about how to configure your firewall.
 Make sure Remote Filtering Client is not installed on the Remote
Filtering Server machine. An instance of Remote Filtering Client running
on the Remote Filtering Server machine eventually uses all available
connections to the server. When the connections are not available, remote
workstations cannot connect to the Remote Filtering Server and are not
filtered. Uninstall the Remote Filtering Client from the Remote Filtering
Server machine.
Remote filtering is not working
If you installed the remote filtering components, but the user workstations on
which you installed the Remote Filtering Client are not being filtered
properly, you may have one or more of the following problems:
 You do not have the correct subscription key to enable the remote filtering
service.
 Remote Filtering Server is not running.
 Remote Filtering Server and Filtering Service are installed on the same
machine.
 Firewalls located between Remote Filtering Server and the Filtering
Service have not been correctly configured.
 The external network firewall and any additional firewalls located
between the Remote Filtering Server machine and the remote
workstations have not been correctly configured.
