    (Wireless) ADSL VPN Firewall Router with 3DES Accelerator Virtual Server (“Port Forwarding”) In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”.

  • Page 111 (Wireless) ADSL VPN Firewall Router with 3DES Accelerator In addition to specifying the port number to be used, you will also need to specify the protocol used. The protocol used is determined by the particular application. Most applications will use TCP or UDP, however you can specify other protocols using the drop-down Protocol menu.

    (Wireless) ADSL VPN Firewall Router with 3DES Accelerator Dynamic DNS The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time.
