The gateway is an IP address (four numbers separated by periods) that indicates the gateway router, also known as the default router.  All traffic that goes outside your LAN (for instance, to the Internet) is sent through this router.  In rare circumstances, you may have no router; in that case, you can leave this blank.  If you don't know the proper answer to this question, consult your network administrator.
