2.4 NAT
Network Address Translation (NAT) allows multiple users at your local site to access the Internet through a single Public IP Address or multiple Public IP Addresses. NAT provides Firewall protection from hacker attacks and has the flexibility to allow you to map Private IP Addresses to Public IP Addresses for key services such as Websites and FTP.
Parameter | Description |
2.4.1 Address Mapping | The Broadband router allows one or more Public IP |
| Address(es) to be mapped to a pool of local Private IP |
| Address(es). This feature is particular useful when you |
| have multiple global IPs and want to divide local users |
| into different groups. |
2.4.2 Virtual Server | You can have different services (e.g. email, FTP, Web |
| etc.) going to different service servers/clients in your |
| LAN. The Virtual Server allows you to |
| particular service port number (from the Internet/WAN |
| Port) to a particular LAN IP address and its service port |
| number. |
2.4.3 Special Applications | Some applications require multiple connections, such as |
| Internet games, video conferencing, Internet telephony |
| and others. In this section you can configure the router |
| to support these types of applications. |
