Do I need a default route out of my containers?

[nifr]

You need to route all traffic to docker's IP addresses through the tuntap interface like this:

sudo route add -net 172.16.0.0 -netmask 255.240.0.0 10.0.75.2

Needs to be done after every host restart obviously.

For some reason I occasionally need to remove the routing and add it back again if I can't connect to the containers anymore.

sudo route delete -net 172.16.0.0 -netmask 255.240.0.0 10.0.75.2
sudo route add -net 172.16.0.0 -netmask 255.240.0.0 10.0.75.2

Hope that helps :)

@nifr thanks for the help

@blairexico no you do not need a default route out of your containers. They should already be setup to communicate out over the host. The fundamental issue is that on macOS docker doesn't support communicating in out of the box which is what theses scripts are designed to help setup.

Have you read the README file of the project? there is a pretty good explanation there of what the scripts do and what additional steps you need to take. Let me know if you find the README insufficient and what doesn't make sense.
