DUAL WAN E2000 / WRT320N

From DD-WRT Wiki

DUAL WAN E2000 / WRT320N

I`m Using "DD-WRT v24-sp2 (04/11/11) mini - build 16773M NEWD-2 K2.6 Eko"

First Approach to "Dual Wan" on this models is to have clear the standards vlans & ports defalt configuration :

E2000 Default Port & Vlan Asignation.

root@DD-WRT:~# nvram show | grep vlan.*ports
vlan2ports=0 8
size: 19998 bytes (41442 left)
vlan1ports=4 3 2 1 8*

It means : Physic port 0 (WAN) = WAN port Logic
Physic port 4 = LAN port 1 Logic
Physic port 3 = LAN 2 Logic
Physic port 2 = LAN 3 Logic
Physic port 1 = LAN 4 Logic
Port 8 = It has to be present en every VLAN since it is a logical bridge

Next Step is to have clear port membership on every VLAN.

root@DD-WRT:~# nvram show | grep port.*vlans
port5vlans=1 2 16
port3vlans=1
port1vlans=1
port4vlans=1
port2vlans=1
size: 19998 bytes (41442 left)
port0vlans=2

It Means : Ports 3 , 1 , 4 and 2 belongs only to VLAN 1
Port 0 (WAN) belongs to VLAN 2
Port 5 Vlans is an internal port just for bridging and you don have to consider this port.

Next Step is to have clear the Name of the vlans in Logical inteface name.

root@DD-WRT:~# nvram show | grep vlan.*hwname
size: vlan2hwname=et0
19998 bytes (41442 left)
vlan1hwname=et0

It means VLAN1 & VLAN2 are part of interface ETH0
