Identifying the Filtering Service for the Block Page URL
If the Filtering Service is installed on a multihomed machine (with two or more
network interface cards), you must identify the Filtering Service by its IP
address in your network so that Websense block messages can be sent to users.
When Websense software blocks an internet request, the user’s browser is
redirected by default to a block message page hosted by the Filtering Service.
The block page URL typically takes the form:
http://<WebsenseServerIPAddress>:<MessagePort>/cgi-bin/
blockpage.cgi?ws-session=#########
If the Filtering Service machine name, rather than the IP address, is contained
in the block page URL, users could see a blank page instead of the block
message that tells them why the site is blocked.
Identify the Filtering Service by IP address to ensure that block pages display
correctly on users’ workstations:
 If you have an internal DNS server, associate the machine name of the
Filtering Service machine with its correct (typically internal) IP address
by entering the IP address as a resource record in your DNS server. See
your DNS server documentation for instructions.
 If you do not have internal DNS, add an entry to the eimserver.ini
file by following these instructions:
1. On the Filtering Service machine, go to the
\bin folder in the
Websense installation directory (by default,
Websense\bin).
2. Make a backup copy of the
eimserver.ini file and store it in
another folder.
3. Open the original
eimserver.ini file in a text editor.
4. In the
[WebsenseServer] area, enter the following command on a
blank line:
BlockMsgServerName=<IP address>
where <IP address> is the correct (typically internal) IP address
of the machine running Filtering Service.
Important
Do not use the loopback address 127.0.0.1.
