I am building an internal whitelist browsing filter server for a business. It is 95% operational. PowerDNS intercepts the DNS request and the LUA script correctly determines if the URL is whitelisted. The problem lies in the blacklist block page ... all I get is PAGE CANNOT BE DISPLAYED. The LUA script is getting to this line but the actual redirect never occurs:
return 0, {{qtype=pdns.A, content="1.2.3.4"}}
The 1.2.3.4 is where I put the actual IP of the PowerDNS server itself. Apache is not detecting that anything is getting to the server over port 80. If I navigate to 1.2.3.4 I do get the block page so I know apache is configured correctly and I have ServerAlias set to * to accept all domains. Thanks in advance.

  1. First of all, you should be sure that domain resolved correctly using something like:

nslookup example.com

  1. Secondary, DNS-cache on the client computer may prevent correct resolving;

  2. You should use 443 port additionaly to 80 for https browser connections;

I have the simular schema with powerdns+lua+nginx and everything work fine. If you have no connection to the apache, that's mean your browser does not resolve domain correctly.
