Restricting access of local PCs to the Internet
Under the general heading Firewall the Gigaset Router offers the following protection
functions:
◆ Complete isolation of a PC
This allows you to prevent any access at all to Web pages from a given PC. To do this
use the functions on the Firewall – Access control page.
◆ Blocking certain URLs
– Keyword filtering
This allows you to prevent the opening of Web pages whose URL contains certain
keywords that you have defined.
Example: Keyword abcd
This would block a website with the URL http://www.abcd.com
– URL filtering
This allows you to prevent the displaying of a website with a particular URL
address.
Example: URL http://www.abcd.com/products
This would block precisely the Web page http://www.abcd.com/products.
– Domain blocking
This allows you to block a particular URL address and all the subsequent addresses
that begin with the same sequence of characters.
Example: Domain http://www.abcd.com
All Web pages beginning with http://www.abcd.com would be blocked, e.g.
http://www.abcd.com and also http://www.abcd.com/products,
http://www.abcd.com/service, http://www.abcd.com/products/
product_graphics1.htm etc.
To do this use the functions on the Firewall – URL blocking page.
◆ Time limits for blocks
You can define a particular block period or a schedule during which certain blocks
become active. You can include the four block strategies described above in this
schedule.
To do this use the functions on the Firewall – Schedule Rule page.
