Does your system as the following sample ?

eg : 
For Public IP ( from ISP ) : 
IP range : 202.175.123.123 ~ 202.175.123.129 ( I want to use
202.175.123.123 trasnfer to 192.168.0.1 Server machine )
    

Your router needs to associate those last two addresses together.  Are
you using a configurable one?

Depending on your network, you might connect 202.175.123.123 to
192.168.0.1 with rules.  You might set that computer to use
202.175.123.123 as its address, directly.  If you have a series of
public addresses that you can use, you *can* use them directly.

  

subnet mask : 255.255.255.240 ( I want to trasnfer to 255.255.255.0 )
    

Don't know what you mean.

  

Router IP : 202.175.123.128 ( So, how to trasnfer to 192.168.0.254,
due to via the Router machine first ! )
    

Can't understand that, either.  It's an incoherent mix of words.

How is your network physically set up?  Do you have a modem connected to
a router, connected to a network of computers?  Is the modem a
combination modem and router?  Is your router a "router" or a computer
working as one?  How are the other computers connected?

  

For Private IP ( All of Server under LAN environment ) : 
IP :  192.168.0.1 ( I want to tranfer to 202.175.123.123 ) 
subnet mask : 255.255.255.0 ( I want to tranfer to 255.255.255.240 ) 
Router IP : 192.168.0.254 ( I want to tranfer to 202.175.123.128 ) 

For Client IP ( via NAT + DHCP of the Server ) : 
Ip : 192.168.1.1 ~ 192.168.1.50
    

Don't know what you mean.  You want to set up a DHCP server to dole out
those addresses?  You want to enable NAT?

  

For sample :
IP range : 202.175.123.123 ~ 202.175.123.129
subnet mask : 255.255.255.240
Router IP : 202.175.123.128

Now, I'm setting up a Internet Server ( all service in the same machines ) :
There are Ethernat 0 and Ethernet 1 two Interfaces with the Server :
Ethernet 0 for connecting with HUB_A and Router, but want to use Private IP address ( eg : 192.168.0.1 ) instead of public IP ( eg : 202.175.123.123 )
Ethernet 1 for connecting with HUB_B, provide NAT + DHCP for Clients ( ip range : 192.168.1.0 / 24 )

So...how to config the firewall rules by using iptables as the following condition :
1, how to clear up the default setting ?
2, how to disable all services ?
3, how to enable the service which needed ?
4, how to transfer the ip address ( public from / to private ) ?
5, how to enable NAT + DHCP for clients users connection with Internet ?
