Can RPZ respond or filter the outbound queries? I would like to apply action and trigger policy to the outbound queries. For example: to PASSTHRU or Drop all outbound queries whose qtype==2 and dst is ¡®xx.xx.xx.xx¡¯. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>If it works, another question is that dose this built-in filter impact the NS selection algorithm of that resolver. Because if you drop all outbound NS query to particular server, the resolver will not (or much less) send any other type of queries to that server. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>My requirement is simple that the resolver can send all types of query except for NS query to that specific server(s). Iptable or other firewall can drop the packets but I would like that action will not reduce other queries to that server(s). <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I¡¯m not sure I make the question clear.
