To activate the change run the following commands: # Disable PF if it was enabled before Remember: en0 is the Wifi network with internet connection, en4 is the local network connection. To do this, add the following line to /etc/pf.conf: nat on en0 from en4:network to any -> (en0) Apple changed the way NAT works quite often over the last versions of OSX. This can be accomplished with the following command: $ sudo sysctl -w .forwarding=1

So using networksetup is the better option. Note: ifconfig would work as well, but can be overwritten by the network settings. You can set this static IP address either via the network settings or via the Terminal: $ networksetup -setmanual "Ethernet" 192.168.3.1 255.255.0.0 A network interface (en4), connected to the network which needs to be connected to the internet has a static IP address 192.168.3.1. I assume your Mac (=router) has a Wifi connection to the internet (en0, configured with upstream DHCP). Setting up NAT by appealing to the core of OSX is not that hard. Sure, there are the sharing options, but they're quite limited and bring their own DHCP server, with no control over it anymore. Configuring a Mac (Macbook Pro in my case) to act as a NAT router is hairy as well. That's why I wrote an own small DHCP server recently.

Set up Internet Sharing on Mac OSX using Command Line Tools July 3rd, 2017.Įven if Mac-OSX has a Unix core, Apple put some layers on top of it, which makes it rather hard to freely hack around.
