internet connection issue

[Scott Moseman]

Do you use a managed switch that would allow you to setup port sniffing?
I would sniff packets on the machine and gateway ports to see if both,
one or neither of them are seeing the packets from the machine in
question.  This could help you narrow down *where* the problem exists;
machine, switch, or gateway.

Thanks,
Scott

Subject: internet connection issue

Hi all,
I have tried all I can, I think I need some help. I have a machine
connected to the Lan and the Internet. The Lan is fine..I can connect to
all services on the network.
However, the issues is on the internet part of the network. I put all
the detail on the card, but i can't seem to reach the gateway when i
ping. I have checked the routing table that is fine. I tried another nic
i.e. that of the Lan which workd well but i still can't reach the
gateway. I connected a windows box and i can reach the gateway. I clone
the windows mac address i still can't reach it. I have stopped iptables
just to test, but still can't reach the gw. 
Has anyone seen this issue before? I am short of reinstalling the system
but i have a feeling that might not solve my issue.
Thanks
