I'm using the command "netstat -nr" to view the host routing table on a Mac OS X system, and here's the output I'm getting:

Can anyone tell me what the "0/2" destination in the first line means?

I would assume it means route 0.0.0.1 - 63.255.255.254 via 192.168.1.1 on interface en0. That's what it would mean in the non-apple world. No idea WHY is would say or do that but those utun0 lines look weird too.

  • You're right - we had a typo on the OpenVPN routes that was causing the route to be installed after connecting to the VPN. – slantalpha Oct 10 '17 at 04:37
