For testing we need "emulate" 16 machine. One of the requirement is the asynchronous. This means the one NIC network gateway is not acceptable. So we need one multiprocessor server with 4 nic. But we require this 4 nic in a same subnet.
Configuring of is done and working fine with external workstations.
But the internal traffic is not flow trough the exteranal interfaces.
For example the NICs:
eth0 192.168.1.151 00:00:00:00:00:01
eth1 192.168.1.152 00:00:00:00:00:02
eth2 192.168.1.153 00:00:00:00:00:03
eth3 192.168.1.154 00:00:00:00:00:04
For example the ping -I eth1 192.168.1.151 is not responding.
The first problem is the ARP is not responding in this example at eth0.
If we add arp entry manually then looks like the icmpreq go out eth0 and eth1 too and no response for.
The kernel is 126.96.36.199 .
