Hi All,

I am having issues with getting DNSFW to work properly, it fails in many 
conditions to block things from the list.

The dbl list works fine for me in the URL Filter for both CU200 and CU201 
Testing.

For my testing I created a new install of CU201 Testing and just went straight 
to DNSFW and enabled the Gambling and Pornography categories and Saved.

Then selected the Green network for both categories using the pencil edit 
option.

In this setup I had no Web Proxy enabled.

I then cleared the browser cache and set the Browser to No Proxy.

I then tested out nl.onecasino.com and www.xnxx.com in Firefox and in Netsurf

The gambling site was blocked and gave the message

Unable to connect
Firefox can’t establish a connection to the server at nl.onecasino.com.

For the porn site it was not blocked but opened up.
I tried with two other gambling and porn sites. All three gambling sites were 
blocked. All three porn sites were allowed through.

In the DND: Unbound System Logs I found

12:52:26 unbound: [1820:0]  info: rpz: applied [gambling.rpz.ipfire.org] 
*.postcodeloterij.nl. rpz-nxdomain 192.168.200.11@44247 www.postcodeloterij.nl.

So the blocked gambling sites were in the logs but not any of the pornography 
sites  had tested.

Then tried the browser with the Network Settings set to Use system proxy 
settings and the same result occurred.

I then turned on the Web Proxy with conventional connection on port 800. Saved 
and restarted and then Cleared the web proxy cache.
Then I cleared the browser cache and set the Network Settings to Manual proxy 
configuration with the IP of my IPFire system being tested.

I then tested the same three gambling URL's and Porn URL's.
All of the sites were opened up.
In the DNS: Unbound system log there were no new entries.
In the Proxy Logs there were entries for the gambling and porn sites.

I have also tested the browser out using the web proxy with the Automatic proxy 
configuration URL accessing the wpad file via dhcp and that also had the same 
results as using the Manual proxy configuration option.

I have repeated a lot of my tests multiple times, also with repeated new 
installs and for me, as long as I ensured I had cleared the web proxy and 
browser caches, always came up with the same results as I have described above.

It would be good to know if any of you also experience the same effect or if it 
works without problems for yourselves.

Regards,

Adolf.
