If any voice gateway device (e.g., VigorPhone 350) wants to register extension on
VigorIPPBX 3510 through WAN interface remotely, such registration can be done easily if
the public IP address of the VigorIPPBX 3510 is entered into the remote device. However,
any clients can ask for registration of extension to VigorIPPBX 3510 easily. Therefore, it is
not safe due to the low security and the network shall be the object that hackers attack.
To enhance the security of the extension registration through WAN interface, a new function
of ACL is supported by VigorIPPBX 3510. The purpose of this function is to type the public
IP of the remote device on VigorIPPBX 3510. Later, such remote device can register the
extension on VigorIPPBX 3510 through WAN interface. That is, only the specified IP
address can register the extension on VigorIPPBX 3510.
The network architecture can be described as follows:
Hence, when you want the remote device registering the extension to VigorIPPBX through
WAN interface, you can use ACL function to finish it.
