hi guys!
Im using ipcop a couple of months now as my firewall, i configured it and run smoothly as i expected. But suddenly it stop working, i checked it and found out that 1 of the 3 NICS is not working, i replaced the NICS pci slots from 1 to another, but its the same problem 1 of the NIC is not detected. I reinstalled my ipcop all 3 NICS are detected, but minutes after, it stop working again.
I tried to installed other distro like slackware, fedora and rhel3, NICS are detected but its the same problem in ipcop (replaced the NICS, it works a minute but still stop working, but all my NICS are working fine in windows.

)
i dont know what im going to do now.
please help!
