I have a multi boot system with Win XP, SuSE 9.2, Ubuntu 4.10, which is hooked up to the DLink 502T ADSL modem/router provided by MTNL (no wiring issues). WAN IP is dynamic, LAN IP is 192.168.1.1. DHCP server is enabled on the router to dish out IP numbers.
When I boot to SuSE or Ubuntu, or Knoppix 3.6, I am unable to connect to sites on the Internet (POP3, SMTP, HTTP etc.) using Konqueror or Firefox. When I point my browser to mumbai.mtnl.net.in or mail.yahoo.com, the status bar says "Connecting to ...." and eventually times out.
I am able to resolve DNS names (using MTNL's DNS servers). I am able to ping certain hosts in the MTNL network such as mumbai.mtnl.net.in, their gateway, etc.
Firewall is disabled (iptables rules allow everything). The routing table also seems to be OK (see output below).
However, when I boot the same system to Win XP. I am able to connect and browse sites on the 'Net.
Another interesting point, when I connect the system to another ISP Iqara (similar setup as MTNL i.e. a cable modem/router with DHCP) I am able to browse sites under Linux as well as Win XP. Note: in both cases the system is getting it's network params from the router's DHCP server).

The problem was the DLink modem/router. After my original post, it exhibited more symptoms of Alzheimer's disease - it failed to act as a DNS relay or not transfer all the images from a web site etc. It finally RIP on Sunday (no puns intended).
BTW, I could not get thru any of MTNL's help lines or email support (no surprise here). Reporting a trouble on xxxx-2198 (xxxx is your 4 digit exchange no.) was not much use. I finally went to Khar (w) exchange and asked to see their local DSL manager. He was very cooperative and asked me to bring in the failed unit. Upon furnishing it, he got it tested and replaced it within an hour. If you want quick resolution on MTNL DSL hw issues do not waste time calling. It is best to take the hw to your respective exchange (with a letter stating the problem). Most likely they will do a swap within an hour.
Erle and Derwyn thanks for helping me debu
