My nethserver has been setup in AWS.
I started initially with a single red interface (Which can be switched only with the new servers manager at 9090 and not with 980 since 980 says you need a green interface always).
This only red interface configuration is required in AWS since we are not using the LAN.
But this causes problems with ipconfig throwing some error while the template is expanded and then shows that Yum cache clearing will help (it doesn’t).
Only adding a new network interface and saving it as green fixed the issue. This is not a problem since you don’t have to pay for network interfaces on AWS but I feel this extra step is unnecessary.
What I need is to know how to configure Nethserver with only a red interface and still make is work. This can increase the adoption in AWS for mail, VPN and other needs.
