I have a DL360 with 2 Tigon gig NICs(eth0 & eth1) and 1 Fast Ethernet Quad CARD (E100). I'm using the 2 Tigons and the second port(eth3) of the Quad Card. These 3 are connected to switches and have been up and running for 5 weeks. I have a standalone PC (Dell GX1) which I put into the first NIC(eth2) of the Quad Card. I was able to ping from the Netfilter Server to the standalone PC. When I pulled the Xover cable out of the Quad Card(gently). The Netfilter Server's desktop locked up and routing between the established LANs stopped. I had to depress the power buttom to recover the system. Before putting this system in Production I tested each NIC by connecting two laptops via Xover cables to separate NICs on the Server. Then I ping'd across the Netfilter Server successfully.
