I have two DELL servers with two Ethernet ports in it. Bith servers have CENTOS 4.5 installed. First Ethernet port connect to public Ethernet line and work correctly. Second Ethernet port I connect point-to-point as private Ethernet (cable direct connect without router or switch). Private Ethernet use IP asddress 1.1.1.1 and 1.1.1.2.
I check "ifconfig -a" and both eth0 and eth1 are up and active. when I tried to ping another server use second port (private) and no response. Does anything I configure wrong?
Thanks.
