Airtel won't working on LAN

["thanigai rajan" <methanigai@gmail.com>]

Hi all,
Our Airtel ADSL2 220BX  Modem has an IP address of 192.168.1.254
my system  has an IP Address of 192.168.1.1 (which has got 2 network cards)
and my LAN machines has got addresses as 192.168.0.0/24
while i set the machine (which has got the IP of 192.168.1.1 & 
192.168.0.1 )as gateway for 
my 192.168.0.0/24 networks, internet is not working in 192.168.0.0/24 networks but working on 
192.168.1.0/24 networks.

but in VSNL the same setup is working fine.

while i go through in both modems the Airtel has firewall enabled but in VSNL the firewall is disabled.

is it the cause ? how to disable it ?
or else what will be the problem?
