Portmaster – Open-source network monitor and firewall
&gt; Phone routing can&#x27;t be blank<p>&gt; Country does not match with the country prefix for your phone number<p>Fishy.<p>And if you check country prefix with the list of country prefixes anyway... Why do you even bother with country AND prefix?<p>&gt; The Portmaster actually handles DNS itself and will show you DNS queries in the UI<p>Yikes.  
What about the DNS resolvers configured in the system? Do you hijack&#x2F;overwrite them? [0]  
I use my own Unbound locally, how Portmaster would handle queries for NSs in the Unbound config which are unknown to the world - leak them?   
How about QNAME minimization?  
Where exactly Portmaster would send the DNS queries?<p>Actual kernel module on Windows so it really can do anything it wants and wouldn&#x27;t be catched by the machine itself?<p>Yikes.<p>Overall, this is the product which could be useful for many users, but for me it&#x27;s a hard no.<p>The &quot;SPN&quot; idea is interesting, but also raises the questions about who, where and how would control exit nodes.<p>[0] <a href="https:&#x2F;&#x2F;docs.safing.io&#x2F;portmaster&#x2F;settings#dns&#x2F;nameservers" rel="nofollow">https:&#x2F;&#x2F;docs.safing.io&#x2F;portmaster&#x2F;settings#dns&#x2F;nameservers</a> says they are forwarding to Cloudflare by default. &#x2F;Great&#x2F;
