I've not started the firewall (shorewall) yet as I cant make a connection with Linux. However, I've checked with 'iptables -L' to make sure no traffic is blocked.

It is the same NIC I'm using with both Linux & Windows. I believe the MAC address would be same irrespective of which OS I'm using?

Here's something I did trying to outsmart the NTL's dhcp server.
1. Boot into windows and get a lease.
2. Re-boot into linux and set the same config manually (giving same IP address etc.)

still the damn thing doesnt work.
I can see network packets going out but nothing coming back when dhclient is negotiating.
