Hello,

After apply a leased line connection with Internet from ISP, there is a
segemnt IP addresses ( Public IP ) and a Router machine ( can't to be
enabled the firewall function ) by ISP also :

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 ?

Edward.
