3.4.5 VPN
VPN (Virtual Private Network) is a secured and Internet protocol to allow users to access the company
internal network resources outside the company network. If you want to make this function take effect,
check the “Enable” button. Hence, the following fields will be activated.
Username: Enter the username. Maximum input is 63 alphanumeric characters (case sensitive).
Password: Enter the password. Maximum input is 63 alphanumeric characters (case sensitive).
Server IP Address: Enter the IP address of the PPTP Server.
You can obtain Domain Name System (DNS) IP address automatically if PPTP server provides it
when you logon. Or your remote PPTP server may provide you with an IP address of DNS. If this is
the case, you must enter the DNS IP address provided. Please refer to WAN-DNS section for more
details. When you establish a VPN tunnel, the active DNS server is this one listed here, not that one
listed in WAN-DNS section. Because you have established the tunnel with remote PPTP server, your
network is connected to remote network directly. All the outgoing packets from your network will be
sent to the remote network; therefore, you have to set DNS provided by remote network for domain
name and IP address conversion.
This VPN function can connect and establish a PPTP tunnel to remote PPTP server on WAN. So, the
router must connect to ISP first, and then use the PPTP client to establish a VPN connection.
If you have disabled the I-STORM ADSL ROUTER ’s NAT option in the WAN-ISP
section, this VPN function will hence be invalid.
