Alarm Information
None
Handling Process
  • Cause one: There is no reachable route between the user PC and the virtual gateway.

     

    Ping the IP address of the virtual gateway to be accessed on the PC. If the virtual gateway cannot be pinged through, it indicates that there is no reachable route. In this case, check the network connection and routing configurations.

     

  • Cause two: The IP address of the virtual gateway is changed.

     

    Contact the administrator to obtain the correct IP address of the virtual gateway.

     

  • Cause three: The shared virtual gateway is not accessed through the domain name of the virtual gateway.

    Suppose the IP address of a shared virtual gateway is 220.101.30.108 and the domain name is 220.101.30.108/vt1. If a user accesses the virtual gateway through http://220.101.30.108, the prompt "The Web page cannot be displayed" is displayed. The user can only access the virtual gateway through http://220.101.30.108/vt1.

  • Cause four: The domain name of the shared virtual gateway is not configured as a public network address.

     

    Suppose the private IP address of the SVN3000 is 194.10.3.18 and the corresponding public IP address is 220.101.3.18. If the administrator sets the domain name to http://194.10.3.18/vt1, when a user accesses the virtual gateway through http://194.10.3.18/vt1, the prompt "The Web page cannot be displayed" is displayed.

    The administrator should set the domain name of a shared virtual gateway to the public network address, namely, http://220.101.3.18/vt1.

     

Root Cause

Cause one: There is no reachable route between the user PC and the virtual gateway.

Cause two: The IP address of the virtual gateway is changed.

Cause three: The shared virtual gateway is not accessed through the domain name of the virtual gateway.

Cause four: The domain name of the shared virtual gateway is not configured as a public network address
