For some reason users want to allow Internet user to access intranet device, but it often happens to configure the wrong setting is RS series gateway. Following procedure will teach user how to configure the correct setting.
The most possible error should be the Custom Service setting, for example, users would like to redirect TCP 3389 from Internet to LAN device. So he might think to redirect TCP 3389 only from Client Port to Server Port in RS series device’s configuration. So, he will configure it as following display:
But this setting is wrong. User should define the specific port number in Server Port, but he can not also
configure it at Client Port. Because Client Port indicates the initial packet’s port number from client side PC,
but the port number will be given by random, so it is possible to be given any port number during the port range 0 ~ 65535.
So, user should define the Client Port as 0 ~ 65535, it is also the default setting for Custom Service.
Next step user should configure Virtual Server to redirect this port to a specific IP address.When he chooses the Custom Service, system will automatically import the port number to next column, now user only needs to specify the IP address of internal LAN device.
The last step is to enable the rule at Incoming Policy. When user configures Virtual Server ready, the profile will be imported to Incoming Policy automatically as soon as user creates the new entry of Incoming Policy.
Click OK to finish the entire configuration, so Internet user can access the internal device with TCP 3389 port now. |
