Blocking websites by IP address
Posted: Thu Oct 08, 2009 11:32 am
Hi,
We're testing WFilter for implementing black lists URL filtering. It's working as expected, but we found that any URL black-listed can be efectively accessed if the user knows the IP address of the URL and types it on the browser.
For example:
www.imfirewall.us --> 68.178.138.76
The black list includes www.imfirewall.us and it is blocked OK, but if the user enters its IP address 68.178.138.76 the website can be accessed.
We found one workaround. That is to include the IP address 68.178.138.76 in the black list... but this is not practical, as IP addresses usually change without notice.
Is there any way to solve this?
Thanks,
Alejandro.
