something
that I couldn't figure out how to get a ubuntu vm to run with.
In the ubuntu host, the ipip works just fine and there is a module for it.
But the module isn't in the VM and I dont see why.
You probably are not running a full VM (hardware virtualization with a standard OS running
in it)
but paravirtualization like Xen which runs a special kernel in the guest machine.
This is popular for providing virtual webservers and other "cloud" servers.
However, as those servers are normally not full-featured, the guest kernel is compiled
with
limited selections in the kernel config, and it may well be that exotic features like IPIP
tunnels
are not provided in that config.
When it is your own system, you could opt to compile your own kernel and modify the
config
while doing that. It may be easier to run the IPIP tunnel gateway on a dedicated system,
e.g.
a Raspberry Pi (as I do myself) or router (e.g. a MikroTik using Marius YO2LOJ's
method.
