Thanks for your help.
I will try to do it in the server.
Is there any document that should read about this?

Yes.
I plan to use centos as the OS on the gateway server.

So you're trying to determine what you need to do to forward
connections from your system to port 5555 on the remote system via
your gateway it seems. What is your gateway running? Is it running
CentOS?
I would use something like:
iptables -t nat -I PREROUTING -d <public ip address of server> -p tcp
--dport 5555 -j DNAT --to <private IP address of database server>
If you are not already masquerading traffic out, this should handle that.
"iptables -t nat -A POSTROUTING -s <internal network/mask> -j MASQUERADE"
Once you see that work, you can do a "service iptables save" to save the
configuration and "chkconfig iptables on" to make sure it starts on boot.
