•To make it easier for Internet users to connect to your Servers, you can use the "DDNS" feature. This allows Internet users to connect to your Servers with a URL, rather than an IP address. This technology works even if your ISP allocates dynamic IP addresses (IP address is allocated upon connection, so it may change each time you connect).

Servers
Servers | This lists a number of common Server types. If the desired Server |
| type is not listed, you can create a Firewall Rule to achieve the |
| same effect as the Virtual Server function. |
|
|
Properties |
|
Enable | Use this to Enable or Disable support for this Server, as required. |
| If Enabled, you must select the PC to which this traffic will be sent. |
|
|
PC (Server) | Select the PC for this Server. The PC must be running the appro- |
| priate Server software. |
|

For each entry, the PC must be running the appropriate Server software. If the desired Server type is not listed, you can define your own Servers, using the Firewall Rules.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Servers using a URL, rather than an IP Address.
