I am trying to build a GRE tunnel inside an ubuntu container:
root@ny-fw01:/# ip tunnel add netb mode gre remote 100.65.0.6 local 100.65.0.2 ttl 255
add tunnel “gre0” failed: No such device
I am running 1.12.1 beta 24.
The container is run with: --privileged --cap-add=ALL options.
Note that it does work on a linux host (running CentOS). So is there a way to add GRE functionnality inside the MacOS linux virtual machine?
Thanks for your help,
