from what I can say you have messed up the part numbers . If you are using direct mount then part2 will mount as /opt and part3 will mount as /mnt[if your are doing it from scratch] . Since part1 contains the fs.gz so that's the mistake AFAIK.
cd /dev/discs/disc0;ls -lrt
Reset and try again is DHCP enabled ?
yes , it's in router mode , here are the settings i changed and still no result
modem - Bridged
router - PPoe , username / pass + enable DHCP
was using it in PPoe Mode on Asus firmware .
I did see that WAN ip was not assigned . It is 0.0..0.0

So your DHCP settings are okay. The problem lies in dialing and authenticating a connection. When you say it works fine with modem alone, chances are again the problem might be related to MAC binding. Give MTNL a call and ask them to release the MAC binding and see if it works then. There's nothing needs to be changed other than these to make it work in dd-wrt AFAIK.
