Appendix B: Troubleshooting
4. Check that any firewalls located between Websense Filtering Service and
Remote Filtering Server are correctly configured.
If there are one or more firewalls between the Filtering Service machine
and the Remote Filtering Server machine, check that they have been
properly configured, as described in Enabling communication between
Remote Filtering Server and Filtering Service, page 216.
 Make sure the Filtering Service’s Filter port (by default, 15868) has
been opened on all firewalls between the Filtering Service and
Remote Filtering Server. If this port is not open, Filtering Service
cannot accept connections from the Remote Filtering Server.
 Make sure that the Block Page port (by default, 15871) has been
opened on all firewalls between the Filtering Service and Remote
Filtering Server. If this port is not open, Filtering Service cannot send
block pages to remote users.
5. Check that the external network firewall and any additional firewalls
located between the Remote Filtering Server machine and the remote
workstations have been properly configured, as described in Enabling
communication between Remote Filtering Server and Remote User
Workstations, page 216.
 The Remote Filtering Server’s External Communication Port on
these firewalls must be able to accept connections from Remote
Filtering Clients on workstations located outside the network firewall.
By default, this is port 80, unless it was changed during installation of
the Remote Filtering Server.
 Access to the Remote Filtering Server’s Internal Communication
Port must be blocked from workstations located outside the network
firewall. By default, this is port 8800, unless it was changed during
installation of the Remote Filtering Server.
6. Make sure Network Agent is not filtering responses to remote filtering
requests.
Check that Network Agent is not monitoring the machine on which
Remote Filtering Server is installed:
a. Open Websense Manager and connect to the Policy Server.
b. Select Server > Settings.
c. The Settings dialog box appears.
d. In the Settings pane, click Global Settings under Network Agent.
