14 SBG900 User Guide Home X Exit Print Overview Installation Troubleshooting Contact FAQ Specifications Glossary License Configuration: Basic Gateway TCP/IP Wireless USB Port Forwarding Port forwarding is the configuration of SBG logical data ports for applications having special network requirements. The SBG900 opens logical data ports when a computer on its LAN sends data, such as e-mail messages or web data, to the Internet. A logical data port is different from a physical port, such as an Ethernet port. Data from a protocol must go through certain data ports. Here are the data ports used by some protocols: Some applications, such as games and videoconferencing, require multiple data ports. If you enable NAT, this can cause problems because NAT assumes that data sent through one port will return to the same port. You may need to configure port forwarding to run applications with special requirements. To configure port forwarding, you must specify an inbound (source) port or range of ports. The inbound port opens only when data is sent to the inbound port and closes again after a specified time elapses with no data sent to it. You can configure up to 32 port forwarding entries using the Gateway > PORT FORWARDING — config Page. Virtual Private Networks The SBG900 allows multiple tunnel VPN pass-through operation to securely connect remote computers over the Internet through the SBG900.
