or sbc.com:1020.

2.7.9 VPN (Available on the HX4E/MX8A/HX4G/MX8G)
A VPN is a virtual private network constructed on the public network. VPN technology is based on the
idea of tunneling. It performs user authentication and data encryption to prevent data transferred over the
public network from being invalidly browsed or changed. Because the VPN is a logical network
constructed on the public network, it is unnecessary to deploy end-to-end physical links, only the VPN
server and VPN client need to be deployed instead, which greatly reduces the network expense.
With a built-in VPN client, the HX4E/MX8A/HX4G/MX8G is ready to be directly connected to the VPN
server to avoid the firewall issues and NAT issues.
When an untrusted network needs to be traversed between the HX4E/MX8A/HX4G/MX8G and the SIP
server, you are recommended to construct a VPN network, and configure VPN client for
HX4E/MX8A/HX4G/MX8G.
