Hello,

1, There is a registered Domain name for the service.
2, All service under the same server machine and use private address as
the following :

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 )
subnet mask : 255.255.255.240 ( I want to trasnfer to 255.255.255.0 )
Router IP : 202.175.123.128 ( So, how to trasnfer to 192.168.0.254, due
to via the Router machine first ! )

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

Edward.

PS: Due to the Router can't to be enabled the firewall function, so we
can to enable the firewall function by using linux only !
