FYI:以下引自e500 user manual第103頁,另外照manual中看來data service分成standard data service和streaming data service,不知除了封包的優先權及計費方式不同外還有沒有其它差異....
Port forwarding
Port forwarding enables you to setup a server connected to the EXPLORER 500 while the terminal is in Router mode. Without port forwarding it would not be possible to contact the server from the internet.
For information on how to set the terminal in Router mode, see Configuring the LAN interface on page 100.
The following example shows how to allow internet access to a mail server (smtp) connected to the terminal . The mail server in this example has the IP address 192.168.0.100.
