  • Page 105: Virtual Server ("Port Forwarding")

    Billion BIPAC-8500 / 8520 SHDSL VPN Firewall Bridge / Router 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 106 Billion BIPAC-8500 / 8520 SHDSL VPN Firewall Bridge / Router TCP & UDP 1503 1720 4000 7070 Because NAT can act as a “natural” Internet firewall, your router protects your network from being accessed by outside users when using NAT, as all incoming connection attempts will point to your router unless you specifically create Virtual Server entries to forward those ports to a PC on your network.
  • Page 107 Billion BIPAC-8500 / 8520 SHDSL VPN Firewall Bridge / Router For example, if you set the port number 80 (Web/HTTP) to be mapped to the IP Address 192.168.1.2, then all incoming HTTP requests from outside users will be forwarded to the local server (PC) with the IP address of 192.168.1.2.

Universal Plug and Play (UPnP): UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and data transfer between devices. UPnP offers many advantages for users running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by letting the application control the required settings, removing the need for the user to control advanced configuration of their device.
