Virtual / Dummy / Fake Interface?

We have a setup where we are running Astaro in a DMZ with only 1NIC. We want to use Astaro as a VPN gateway where all the clients can reach each other and be protected behind the firewall content proxy before going to the Internet (NAT). This does not seem possible without some work.

So we've tried creating a fake adapter using the following means:


  • ip link add eth-dummy type dummy
  • ifconfig eth0:1 192.168.1.0/24
  • Would have tried VLANs but tagged and untagged frames don't seem to be allowed on the same NIC by astaro.
  • And tuntap, but that does not seem to be available


We don't want our fake internal network to be exposed by the physical NIC if possible (so eth0:1 was worth trying but not desirable.)

Any suggestions?

Thanks.

  • Why do you want to use DHCP?  Since these must be local users on the Astaro, why not assign each of the users a static remote access IP?
