I am sorry have not replied to my original post for my first visit to this bbs.
However, my firewall has been closed early:

[root@greate02 network-scripts]# iptables -nL
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

and I used the same cable to test these netcards.

Please do not post the same thread in more than one forum, or multiple posts on one topic in the same forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
