4 Configure the Internet
If you have local servers for different services and you want to make them publicly ac-
cessible, you need to specify the port forwarding policy. With NAT applied, it translates
the internal IP addresses of these servers to a single IP address that is unique on the In-
ternet.
To the Internet users, all virtual servers on your LAN have the same IP Address. This IP
Address is allocated by your ISP. This address should be static, rather than dynamic, to
make it easier for Internet users to connect to your servers. However, you can use dy-
namic DNS feature to allow users to connect to your virtual servers by using a URL, in-
stead of an IP address.
