If you use a web proxy server on your network and install an IBM Security Network Protection appliance between the proxy server and user workstations, users must configure their web browsers to exclude the IP address of the appliance protection interface from the proxy settings.
If users do not exclude this IP address, the browser is not redirected to the requested website. Instead the browser displays an error page.
Resolving the problem
Users must add the IP address of the appliance's protection interface to the exceptions list in their browser's proxy settings.
