  • Page 92: Virtual Server ("Port Forwarding")

    Technical Reference OPEN824RL / RLW ADSL / VoIP Routers Virtual Server (“Port Forwarding”) In TCP/IP and UDP networks, a port is a 16-bit number used to identify an application program (usually a server) to which incoming connections should be delivered. 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 93: Adding A Virtual Server

    Technical Reference OPEN824RL / RLW ADSL / VoIP Routers Adding A Virtual Server 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 computer on your network.
