I’m trying to connect two virtualmin boxes using a crossover cable. Both boxes have dual Ethernet interfaces, and in both eth0 is configured correctly , I can access them remotely, no problems. Now I want to set them up so they can access each other without going through the datacenter routers/switches that generate bandwidth costs for me.
I have a crossover cable already in place, and I tried to configure the network on both boxes using the webmin Network Configuration option. I’ve set up their eth1 to use an IP like 192.168.16.1 and 192.168.16.2. When I configured the Routing, I used the IP from the other machine as the gateway. Like this:
To my surprise, when I applied this configuration I lost the connection to both boxes. The gateway for the eth0s seemed to have changed as well. I had to have the datacenter support to undo my changes locally so I could get back online.
So, my question is, how do I correctly configure the network / routing so my eth1 cards can talk to each other through a crossover cable, without interfering with the eth0 configuration? Should I use the eth1 gateway the same as the eth0?
Thanks a lot
