intergrated PC NICS can't get through PIX

[scoraymo]

I have several PC's with intergrated network cards that can't get to the internet. If we replace the NIC with a PCI NIC it resolves the problem. Anyone know of a reason what could cause such a problem?

What's the MAC address(es) on the integrated cards? What version of PIX code are you running.

There is a bug in older PIX code where it won't learn MAC addresses in the form 0008.xxxx.xxxx. Bug ID is CSCdt47829 (http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCdt47829)

Are you able to ping the internal ip address of the pix when using the integrated network cards? If not, then there might be some misconfiguration of the linkspeed (10/100Mbit) and the duplex mode (half/full). If the integrated network cards are in autosensing mode, try to change it to a fix setting (eg. 10 Mbit/half duplex).

Kind Regards,
