So I thought the best way to do this actually explain a problem that I'm trying to solve. So here I have a machine it's a docker machine. This is the IP address that is publicly available.

So what I want to do is I want to go on this machine which is my Mac which is outside this machine and I want to be able to access this guy. Currently I cannot of course because this is not aware of this network right so let's let's try it 172.17.0.25432 2 5 4 32 of course it's going to keep trying and there is no way no path to this network. So what if I added a row that says hey if you want to go to this go through this literally that. So this is the command sudo route in add network. If you want to go to this go through this but by adding that and of course is an administrator operation just like that I added a route that says hey if you want to go to that then go through this. Now if I do a till net works.

If this was not enabled, that forwarding would not have
