order they are listed. The ZyWALL checks requests for Web sessions

 

 

against the list of content filter policies (starting from the first in the list). The

 

 

ZyWALL’s content filter feature blocks or allows the Web session according

 

 

to the first matching content filter policy and does not check any other

 

 

content filter policies. The ZyWALL does not perform content filter on Web

 

 

session requests that do not match any of the content filter policies.

web access is blocked by content filter. The web page you specify here
