Proxy Anonymizer Getting Through

Our students have the category Anonymous Proxies blocked in v7.009, but they are still getting to a particular anonymizer:  ninjaproxy.com.

I checked this URL at Astaro's URL checker and it says it is in category: 

For V7:
http://ninjaproxy.com is in our list and categorized as Proxies & Translators


I checked the exception list, too, and didn't find anything that should allow this through. Is there a way to find out what is allowing this through?

Is there anything else I can look at to determine how this is getting through?

  • If you have your proxy as transparent it will not filter the https://ninjaproxy.com website, but if you have in in standard mode it will.  

    I know cause I just tried it.  We are using 7.010
  • The reason for this is that http transparent mode only processes http which means tcp port 80. the url you specified uses https, means tcp port 443. 

    ASG can not yet transparently decrypt ssl encrypted connections, 
    therefore we do not redirect this port.

    if you swich to standard or authentication mode, than we can also https connections like ninjaproxy.com.

  • trkneller have you had any luck with this?  According to the log

    /var/log/http.log:2007:10:18-07:36:57 (none) httpproxy[16692]: id="0001" severity="info" sys="SecureWeb" sub="http" name="http access" action="pass" srcip="an IP" user="some user" url="www.ninjaproxy.com/favicon.ico" method="GET" size="209" 


    Does this not show a fav icon for whom ever this is using an http connection?
    Anyone?
  • Looks like you've got a good point; I can't test in transparent mode right now, but in SSO and Standard mode this is blocked.
