Customizing Keyword Blocking URL Checking
You can use commands to set how much of a website’s URL the content filter is to check for
keyword blocking. See the appendices for information on how to access and use the command
interpreter.
Domain Name or IP Address URL Checking
By default, the ARMOR Z1 checks the URL’s domain name or IP address when performing keyword
blocking.
This means that the ARMOR Z1 checks the characters that come before the first slash in the URL.
For example, with the URL
www.zyxel.com.tw/news/pressroom.php
, content filtering only searches
for keywords within
www.zyxel.com.tw
.
Full Path URL Checking
Full path URL checking has the ARMOR Z1 check the characters that come before the last slash in
the URL.
For example, with the URL
www.zyxel.com.tw/news/pressroom.php
, full path URL checking
searches for keywords within
www.zyxel.com.tw/news/
.
Use the
ip urlfilter customize actionFlags 6 [disable | enable]
command to extend (or
not extend) the keyword blocking search to include the URL's full path.
File Name URL Checking
Filename URL checking has the ARMOR Z1 check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL
www.zyxel.com.tw/
news/pressroom.php
.
Use the
ip urlfilter customize actionFlags 8 [disable | enable]
command to extend (or
not extend) the keyword blocking search to include the URL's complete filename.
NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
Dynamic port mapping
Learning public IP addresses
Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
