16.7 Example: Block LAN Users From Using a Remote WAN
Application
This example shows you how to block LAN users from using a remote WAN application such as
TeamViewer.
Client C1 on the Zyxel Device LAN uses computer A. Client C2 on the WAN uses computer B. Computer
A and computer B are connected to the TeamViewer server (S). Client C1 could access computer B
using TeamViewer. Client C2 could access computer A using TeamViewer. TeamViewer only works if
computer A and computer B are both connected to the TeamViewer server (S).
Figure 171 Content Filter Tutorial Example
You want to block all LAN clients from using TeamViewer. Create a Content Filtering profile that includes
the remote access category. Create a Content Filtering block list rule with TeamViewer as the keyword.
Then apply the profile to the LAN_Outgoing security policy.
Table 132 Security Service > Content Filter > Add/Edit > Test Web Site Category
LABEL DESCRIPTION
URL to test Enter a web site URL in the text box.
When the content filter is active, you should see the web page’s category. The
query fails if the content filter is not active.
Content Filter can query a category by full URL string (for example, http://
www.google.com/picture/index.html), but HTTPS domain filter can only query a
category by domain name (www.google.com), so the category may be
different in the query result. URL to test displays both results in the test.
If you think the category is
incorrect
Click this link to see the category recorded in the Zyxel Device’s content filtering
database for the web page you specified (if the database has an entry for it).
