I coudn't manage to set up basic ip forwarding on OSX Yosemite 10.10.1 Mac-Mini.
I use the exact same configuration on a OSX Mavericks 10.9.5 Mac-Mini, and it's working perfectly ?
I set the
sudo sysctl -w net.inet.ip.forwarding=1
sudo sysctl -w net.inet6.ip6.forwarding=1
sudo sysctl -w net.inet.ip.fw.enable=0
I use two interfaces
one on network with gateway to internet en0 :
ip 192.168.7.7
gateway : 192.168.7.254
one for local purpose only en5 (usb to ethernet)
ip 192.168.54.254
gateway : self
I configure a DHCP on the en5 for delivering ip
192.168.54.0/24
I configure static route on my routeur (192.168.7.254)
Destination 192.168.54.0/24 -> 192.168.7.7
When a device is connected on the en5 interface
- they get a good ip from dhcp (192.168.54.x)
they can ping en5 interface
ping 192.168.54.254 // ok
they can ping en0 interface
ping 192.168.7.7 // ok
But i couldn't achieve to contact any other machine on the 192.168.7.x network, or any ip from outside.
ping 192.168.7.254 // timeout
Here is my route table

Once again i have the exact same configuration on a mac mini on OS 10.9.5 and it's working, ip forwarding have the classic behavior....
Thanks for help.
man sysctlI see this "COMPATIBILITY The -w option has been deprecated and is silently ignored."
