And if the server is in LAN, its IP Address is belonging to Private IP Address. Then the external users cannot connect to its private IP Address directly. The user must connect to the SMC BR21VPN's WAN subnet's Real IP and then map Real IP to Private IP of LAN by the SMC BR21VPN. That is, to map all the service of one WAN Real IP Address to one LAN Private IP Address. Server 1/2/3/4: Its function resembles Mapped IP's. But the Virtual Server maps one to many. That is, to map a Real IP Address to 1~4 LAN Private IP Address and provide the service item in Service. 119 Define the required fields of Virtual Server WAN IP WAN IP Address (Real IP Address) Map to Virtual IP Map the WAN Real IP Address into the LAN Private IP Address Virtual Server Real IP The WAN IP address which mapped by the Virtual Server. Service name (Port Number) The service name that provided by the Virtual Server. External Service Port The WAN Service Port that provided by the virtual server. If the service you choose only have one port and then you can change the port number here. (If change the port number to 8080 and then when the external users going to browse the Website; he/she must change the port number first to enter the Website. ) Server Virtual IP The virtual IP which mapped by the Virtual Server. 120 We set up four Virtual Server examples in this chapter: No. Ex1 Suitable Situation Mapped IP Example Make a single server that provides several services such as FTP, Web, and Mail, to provide service by policy. Page 110 Ex2 Virtual Server Make several servers that provide a single 113 service, to provide service through policy by Virtual Server. (Take Web service for example) Virtual Server The external user use VoIP to connect with VoIP of LAN. (VoIP Port: TCP 1720, TCP 15328-15333, UDP 15328-15333) Virtual Server Make several servers that provide several same services, to provide service through policy by Virtual Server. (Take HTTP, POP3, SMTP, and DNS Group for example) 116 Ex3 Ex4 120 Preparation Apply for two ADSL that have static IP (WAN1 static IP is 61. 11. 11. 10~ 61. 11. 11. 14) (WAN2 static IP is 211. 22. 22. 18~ 211. 22. 22. 30) 121 Example Make a single server that provides several services such as FTP, Web, and Mail, to provide service by policy STEP 1Setting a server that provide several services in LAN, and set up the network card's IP as 192. 168. 1. 100. STEP 2Enter the following setting in LAN of Address function: (Figure10-1) Figure10-1 Mapped IP Settings of Server in Address STEP 3Enter the following data in Mapped IP of Virtual Server function: Click New Entry WAN IP: Enter 61. 11. 11. 12 (click Assist for assistance) Map to Virtual IP: Enter 192. 168. 1. 100 Click OK Complete the setting of adding new mapped IP (Figure10-2) Figure10-2 Mapped IP Setting WebUI 122 STEP 4Group the services (DNS, FTP, HTTP, POP3, SMTP. . . ) that provided and used by server in Service function. And add a new service group for server to send mails at the same time. (Figure10-3) Figure10-3 Service Setting STEP 5Add a policy that includes settings of STEP3, 4 in Incoming Policy. (Figure10-4) Figure10-4 Complete the Incoming Policy STEP 6Add a policy that includes STEP2, 4 in Outgoing Policy. It makes the server to send e-mail to external mail server by mail service. [. . . ] According to the downstream / upstream report of the selected TOP numbering to draw the Protocol Distribution chart. (Figure19-8) Pull-down menu selection ServiceThe report of Communication Service when WAN users use the SMC BR21VPN to connect to LAN service server. DownstreamThe percentage of downstream and the value of each WAN user who uses SMC BR21VPN to LAN service server. UpstreamThe percentage of upstream and the value of each LAN service server who uses SMC BR21VPN to WAN user. [. . . ]
