User manual

• Intrusion Detection System(IDS)

o Detects and notifies an access to unauthorized areas by the access list.

o Recognizes and notifies unauthorized packets by applying the basic intrusion rule

for packets.

o Detects and blocks DoS attacks such as SYN flood.

• Virtual Private Network(VPN)

o The VPN capability creates encrypted ‘tunnels’ through the Internet, allowing

branch offices or remote users to securely connect into the network from off-site.

o Functions as a VPN gateway based on PPTP and IPSec.

o Performs privacy and integrity through VPN tunneling and data encryption.

Data Network Application

Functions as data network applications such as NAT/PT, Firewall, VPN, DHCP, and

Application Level Gateway(ALG)

• SIP Aware Application Level Gateway (ALG)

o This feature takes SIP packets coming to the WAN interface and redirects them to

any SIP user agents connected to the private LAN.

• DHCP Server

o This service dynamically assigns IP addresses to all hosts connected to the private

LAN.

QoS

• Processes priority for layer 2 frames based on the 802.1p standard(Switch function)

• Processes priority queuing for layer 3 packets and for selected IPs. The ToS (Type of

Service) field of the IP header is checked and process according to the priority of the

corresponding routing in the data server.

• Processes priority queuing for layer 4 packets and for RTP packets (UDP/TCP port).

Prioritize RTP voice packets over normal data packets for improved voice quality in VoIP

applications.

DSMI

• This service automatically configures the router to allow for VoIP applications such as

remote IP phones and IP networking, IP Trunking, etc. If the OfficeServ 7200 VoIP

services provided by MCP and MGI use private IP, and they are connected behind the

WIM router’s public IP, DSMI will automatically perform NAPT for signaling and media

data packets for VoIP services.

Management

• Supports a specialist level debugging function through Telnet connection

• Supports configuring and verifying the functional block operations of the data server

through a web-based browser

• Exchanges IDS data and alarm data with the system manager

• Program upgrade

o Upgrades program through TFTP

Upgrades program through HTTP
