Hello, I am a newbie in Linux. I have Fedora 13 OS 32 bits. I am working with PowerDNs and Poweradmin. How can I configure this with PowerDNS? 1. Allow localhost recursion but deny recursion to external clients. Is there a tutorial for that? 2. Set up cache nameserver for localhost (like caching-nameserver in Bind). Is there a tutorial for that? 3. My Master Server with PowerDNS is working well from localhost but external clients cannot access it. I have iptables with these rules: *filter :INPUT DROP [0:0] :FORWARD DROP [0:0] :OUTPUT ACCEPT [0:0] # Keep state. -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # PowerDNS for external clients -A INPUT -m state --state NEW -p udp --dport 53 -j ACCEPT -A INPUT -m state --state NEW -p tcp --dport 53 -j ACCEPT # Loop device. -A INPUT -i lo -j ACCEPT COMMIT Are they ok? Should I add something else in iptables? Thanks
