指点我一下,DHCP配了那里出问题了????

Question

#ddns-update-style ad-hoc;
authoritative;
ddns-update-style interim;
allow client-update;

key dhcp_updater{
algrithm hmac-md5.sig-alg.reg.int;
secret+ts9yev/imkujzmpaug2tg==;
};

zone ntu.com.{
primary 210.29.64.3;
key dhcp_updater;
}

subnet 210.29.64.0 netmask 255.255.255.224{
#default gateway
option routers 210.29.64.33;
option subnet-mask 255.255.255.240;

option domain-name "ntu.com";
option domain-name-servers 210.29.64.33,210.29.64.28;
range 210.29.64.20 210.29.64.100;

我查了一下,没有那里出错,可就是客户机获不到地址.
