Router
• Multiple Network Interfaces:
o 2 WAN Ethernet ports: auto-sensing 10/100Base-T and 10Base-T, supporting
Point-to-Point, Point-to-Point over Ethernet (PPPoE) and DHCP client protocols.
o 1 LAN Ethernet port: Enables a connection with a switch for LAN configuration.
o 1 Serial WAN port: Enables dedicated data line service by being connected with
DSU or CSU, which is a data line device. V.35 serial interface supports Dynamic
Host Configuration Protocol (DHCP), PPP, or Frame Relay Encapsulation.
o 1 DMZ Ethernet port: Enable DMZ connection to protect an internal network
from external hazards. DMZ is a separate LAN port for configuring the device
which requires a free access from outside such as a mail server and web server,
while separating the device from internal devices.
• Subnet Routing – The network interfaces of the WAN1, WAN2, LAN and DMZ are
configured with different sub-network interfaces, which enable them to perform the
routing process with each other.
• Static Routing – The OfficeServ 7200 configures a fixed routing table between each
network interface to process the static routing. In this case, the routing table cannot be
dynamically changed by the routing protocol, and specific routing services will be
provided according to the pre-set routing policy.
• Dynamic Routing – The OfficeServ 7200 supports routing information exchange
protocols to react to the changing network environment more effectively:
o RIPv1, RIPv2: These protocols are widely used for managing the routing
information in a mid-sized independent network such as a group of LANs
o OSPFv2: This protocol is used in a large-sized independent network. A router
detects and reports any change in the routing table or the network to other routers,
thus all routers share the same routing information.
• Performs inter-VLAN routing – Communication between the VLAN groups.
Data Network Security
• Outbound and Inbound NAT/PT
o Controls an access to internal resources through conversion between the Global IP
and Private IP. Network Address Translation and Port Address Translation
services protect devices on the private internal LAN from being exposed on the
Public Network. This service also allows a single public IP address to be shared
among multiple hosts on the internal LAN.
• Firewall
o Access Filtering: Access lists and policies can be implemented to control access to
the Data Server resources.
o DMZ Function: Hosts connected to the DMZ port can bypass the network firewall
making it easier for external clients to access their services. Applications such as
web servers and mail servers are typically connected to the DMZ ports.
o Port Forwarding: This feature allows external hosts on the public network to
access hosts and services on the internal private LAN by forwarding the public
WAN address to a private LAN address based on a specific port
