Client can "ping" to dns server. But client can't ping when use as name server.

Did you open and forward port 53 (TCP and UDP)?

I'm not implement any rule except nat for MASQUERADE.
What must I do on my gateway???

Open port 53 (TCP and UDP) in the router's firewall and forward both ports to your DNS server.

I'm default forward for everything on my gw firewall and on my dns server. But still not work :(

Do you have a static or a dynamic IP? IF you have a dynamic IP, it might have changed in the meantime so that your client uses a wrong IP (besides, it is a bad idea to run a nameserver on a dynamic IP).
