好久没配过DNS了，今天又费了点劲搞定了，记下来。

 

1.在/etc/named.conf 的options字段增加

   options {
        directory "/var/named";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
         // query-source address * port 53;
        forwarders {192.168.0.1;192.168.1.22;};
};

 

2.写配置脚本

  #!/bin/bash

  #打开转发
  echo 1 > /proc/sys/net/ipv4/ip_forward

  #加载模块

  /sbin/modprobe iptable_filter
  /sbin/modprobe ip_tables
  #/sbin/modprobe iptables_nat

  #刷新规则
  /sbin/iptables -t nat -F

  #新规则

  /sbin/iptables -t nat -A POSTROUTING -s 192.168.29.0/255.255.255.0 -j MASQUERADE
