How to Setup 50 WANs on Vigor3900?
Vigor3900 has 5 physical WANs; however, it can be extended to 50 WANs at most by using VLAN
Tagging technology.
Below will show how to achieve 50 WANs setup by one Vigor3900 and two VigorSwitch2260s.
Refer to the following application illustration:
Configuring 50 WAN profiles on Vigor3900
1.
Change mode from Basic to Advance via WAN>>General Setup page.
1
2.
Click OK. Vigor3900 will ask you to re-login.
3.
Delete default wan profiles for wan3, wan4 and wan5 by selecting the wan profile then click
Delete.
4.
Click Add to add new WANs.

5.
Create a new WAN profile named with wan1_1, and set VLAN ID named with 111 based on
WAN Port 1(WAN1). Note that Untag must be set with Disable. It means wan1_1 can accept
the packets tagged with VLAN ID 111. Next, click Apply.
6.
Create other WAN profiles named with wan1_2 ~ wan1_24 (referring to the settings on the
left side of the application illustration) and wan2_1~ wan2_24 (referring to the settings on the
right side of the application illustration) and set them with VLAN ID (112~ 134 and 211~ 234)
by repeating step 4 ~ step 5.
Configuration on VigorSwitch2260
1.
Setup VLAN mode as Tag VLAN.
2.
Click Add to create a New VLAN GROUP via VLAN>>TAG-based Group page.
3
3.
Type VLAN name and VID with 111.

Suppose the physical WAN1 of Vigor3900 connects to Port 26 of VigorSwitch. Port 26
will receive untagged packets (based on profile wan1) and packets tagged with 111 to 134
(based on profiles wan1_1 to wan1_24). Therefore VigorSwitch Port 26 must be the
member of VLAN Group ID 111 to 134.
In Member field, select Port 1 and Port 26 as members of VLAN Group 111. Member
setting means only the selected port number (e.g., Port 1 and Port 26) will receive packets
with VLAN TAG 111 coming from Vigor3900.
In Untag field, select Port 1 as Untag. Untag setting means VigorSwitch will untag the
packets while sending it to Port 1. Because general PC or normal network devices do not
accept VLAN packets, therefore in this example, Vigor3900 WAN1 must be connected to
VigorSwitch Port 26 for receiving packets with tagged VLAN ID.
Since ISP modem usually doesn’t accept tagged packets, we have to set Untag for the Port
(e.g, Port 1) used for ISP modem. Connect ISP modem for wan1_1 to VigorSwitch Port 1.
Create the rest VLAN Groups (total is 24) by referring to the following figure. Please notice
that Port 26 must be selected as the member for each group, for it is the channel for any
packets coming from Vigor3900. As to Untag, when you check Port 2 and Port 26, you have to
untag Port 2; when you check Port 3 and Port 26, you have to untag Port 3; and so forth.

Go to VLAN>>PVID page to set up PVID for each port.

6.
PVID means VigorSwitch2260 will check and add VLAN tags while receiving packets
from Ports.
z ISP modem 1 which connects to Port 1 doesn’t support VLAN Tag.
z While the switch receives packets from Port 1, it will add VLAN Tag 111 to the packets
Then Vigor3900 wan1_1 will receive the packets.
After finishing the configuration for one VigorSwitch, please set for another VigorSwitch with
the same procedure. The file names shall be wan2_1~ wan2_24 and the VLAN ID shall be set
as 211~ 234.
