Virtual Private Network (VPN)
VPN function
The system provides the private network function by using the Internet that is an open
network based on the. OfficeServ 7100 provides the VPN gateway function based on
the IPSecurity (IPSec), which is useful to build the enterprise network with reduced
cost and enforced security by using the public network such as Internet rather than the
dedicated network.
VPN Tunnel Mode
This mode processes the VPN function by configuring the tunnel between the VPN
gateway and the gateway in each data module of OfficeServ 7100. Up to 100 VPN
channels are available for one VPN.
PPTP
PPTP is a tunneling protocol for using the IP-based network. PPP encapsulates the
data by wrapping the data with PPP header. PPTP is a protocol that reconfigures the
packets by adding Generic Routing Encapsulation (GRE) header and IP header to this
so that the packets can be transmitted via IP inter network.
L2TP
L2TP is a protocol that combines PPTP and Layer 2 Forwarding (L2F), which collects
the strong points of PPTP and L2F. That is, it encapsulates a user PPP frame, which is
a Layer 2 frame, in an additional message called L2TP and then transmits it to the
device connected to the public network such as IP, X.25, frame relay, or Asynchronous
Transmission Mode (ATM).
4.3.4 Data Applications Functions
DHCP
OfficeServ 7100 can assign the IP address by operating the DHCP. When using the DHCP
server in another subnet, OfficeServ 7100 supports the DHCP relay function.
The IP address of the IP equipment connected to OfficeServ 7100 is can be easily managed.
SIP Aware ALG (SIP Application Gateway)
This function is used for re-creating packets for the smooth communication by checking
the SIP signal process packets according to the NAT/PT table in the data server.
When using the data server of OfficeServ 7100, the SIP equipment can operate regardless
of the packet blocking cased by the firewall or the MAT/PT conversion.
System Management Interface
This function allows the administrator to report and manage the alarm, event, traffic, and
logging information including the IDS information of the data server into the system
administrator package through the TCP/UDP. Whether to report can be optionally specified
based on the management data type.
