Hi all.

I'm trying to bring an Amazon VM into the LAN by following this guide 
[0].  However, it appears that OpenSSH on either RHEL7 or CentOS7 is 
broken as it is not creating tap interface but tun interface.  I've 
tried this on both CentOS5 and CentOS6 and they both work as 
advertised!  Downgrading the OS is not an option!

CentOS5/6 gives me:
tap1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500
  link/ether 9e:9e:44:9e:49:4c brd ff:ff:ff:ff:ff:ff

CentOS7 gives me:
tun1: <POINTOPOINT,MULTICAST,NOARP> mtu 1500 qdisc noop state DOWN mode 
DEFAULT qlen 500

So, what's broken in 7 - or is it that it requires something different?
