Filter
While the port-forwarding feature (available to a SIP-based gateway device) allows another user
on the WAN side of the network to access a PC or server located on the LAN side, our gateway
device provides a feature to prevent such access by specifying the IP address of the WAN side
users using the IP filter function. In the same manner, system supervisors can use this function to
prevent LAN users from accessing certain destination IP addresses.
