NBG-419N v2 User’s Guide

Since the Router checks the URL’s domain name (or IP address) and file path separately, it will not 
find items that go across the two. For example, with the URL 

www.zyxel.com.tw/news/

pressroom.php

, the Router would find “tw” in the domain name (

www.zyxel.com.tw)

. It would also 

find “news” in the file path (

news/pressroom.php

) but it would not find “tw/news”.
