Thread: Configuring Dlink DI-LB604

I am using DLink DI-LB604 ( IP Address 192.168.0.1)
Firmware Version: v.1.02 Built Date: May 18 2009

WAN 1 MTNL DSL Connection 192.168.2.1 (Sterlite SAM300AX ADSL router)
WAN 2 Airtel DSL Connection 192.168.1.1 (Beetel 110BX1 ADSL2+ router)

Both Connection Work properly independently .
I have Configured WAN1 & WAN 2 As Static IP's
MTNL (WAN1)
IP address 192.168.2.1
Subnet Mask 255.255.255.0
Gateway 192.168.2.1

AIRTEL (WAN2)
IP address 192.168.1.1
Subnet Mask 255.255.255.0
Gateway 192.168.1.1

Airtel does not work in Load Balancing mode / or Failover Mode. but if i connect it directly to the switch then machines work with these settings
[AIRTEL]
IP address 192.168.1.x
Subnet Mask 255.255.255.0
Gateway 192.168.1.1]

Local Machines are Configured as 192.168.0.x
Subnet Mask 255.255.255.0
Gateway 192.68.0.1

so i need to configure airtel as pppoe or configure ir in bridge mode.
Connection MAP:
Router 1-------|
|-- DI-LB-604 --->Dlink Gigabit Switch
Router 2 ------|
Thanks
