linux搭建局域网域名访问

# 示例：在BIND DNS服务器上添加域名解析记录
zone "example.com" {
    type master;
    file "/etc/bind/db.example.com";
};

# 编辑db.example.com文件，添加A记录
$TTL 86400
@       IN      SOA     ns1.example.com. admin.example.com. (
                        2023010101      ; Serial
                        3600            ; Refresh
                        1800            ; Retry
                        604800          ; Expire
                        86400           ; TTL
                )
        IN      NS      ns1.example.com.
ns1     IN      A       192.168.1.1
www     IN      A       192.168.1.2

# 示例：在ISC DHCP服务器上配置DHCP池
subnet 192.168.1.0 netmask 255.255.255.0 {
    range 192.168.1.10 192.168.1.100;
    option routers 192.168.1.1;
    option subnet-mask 255.255.255.0;
    option domain-name-servers 192.168.1.1;
}

# 示例：在iptables中配置NAT
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
