I have a server (4 NIC ports 192.168.100.100-103) that connects point to point to a storage device (same thing 4 ports 192.168.110.100-113) but this server connects to normal LAN 10.6.100.x - gateway 10.6.100.1
the issue is when testing connectivity to the storage device everything is cool
but as soon as I set the LAN IPs (10.6.100.x) and the gateway I lost connectivity to storage device
Don't enter or alter any gateways or other routing information.
No routing whatsoever is needed to talk over a point-to-point link, or over the local subnet -- routing and gateways only get involved for things beyond the local network.
All that's needed for two computers connected loopback to ping each other, for instance, is:
The OS will automatically pick the right interface for local traffic based on IP address and subnet mask.
I found something this server has 4 interface the ones 192.168.128.100-103 - eth0...eth3.... but only eth0 is responding
eth0 - 100
eth1 - 101
eth2 - 102
eth3 - 103
the test I am doing is I connect cable to eth1 and I ping 192.168.128.101 and I get no respond but If I connect cable to interface eth0 I get response from 192.168.100.101-102-103....
but If I connect back to eth1 I don't respond from any IP
thanks
any idea why? it's like eth0 activates all the IPs

My router receives the port 80 call, routes it to my server and the world can see domain.com perfectly fine.
However, we cannot see... (3 Replies)
