Vigor3910 Series, a broadband router, integrates IP layer QoS, NAT session/bandwidth

management to help users control works well with large bandwidth.

By adopting hardware-based VPN platform and hardware encryption of AES/DES/3DES, the

router increases the performance of VPN greatly and offers several protocols (such as

IPSec/PPTP/L2TP) with up to 100 VPN tunnels.

The object-based design used in SPI (Stateful Packet Inspection) firewall allows users to set

firewall policy easily. CSM (Content Security Management) provides users control and

management in IM (Instant Messenger) and P2P (Peer to Peer) more efficiency than before. By

the way, DoS/DDoS prevention and URL/Web content filter strengthen the security outside

and control inside.

Object-based firewall is flexible and allows your network be safe.

Before starting to configure the router, you have to connect your devices correctly.

1. Connect a modem to any WAN port of Vigor3910 with Ethernet cable (RJ-45) to access

Internet.

2. Connect the other end of the cable (RJ-45) to the Ethernet port on your computer (that

device also can connect to other computers to form a small area network). The LAN LED

for that port on the front panel will light up.

3. Connect a server/router (depends on your requirement) to any WAN port of Vigor3910

with Ethernet cable (RJ-45). The WAN LED will light up.

4. Connect the power cord to Vigor3910’s power port on the rear panel, and the other side

into a wall outlet.

5. Power on the device by pressing down the power switch on the rear panel. The PWR LED

should be ON.

6. The system starts to initiate. After completing the system test, the ACT LED will light up

and start blinking.

Below shows an outline of the hardware installation for your reference.
