You need to load the tun module ipsec.o
to have
a virtual tunnel interface and kernel support for ipsec.
To accomplish this, you need the appropriate modules tarball for your LEAF Bering-uClibc. It's usually available for download in our FRS, older versions are available in our cvs repository.
Unpack the modules tarball and copy
2.4.32/kernel/net/ipsec/ipsec.o
to
/lib/modules
on your router.
You don't need to put it in /etc/modules
as the
ipsec init script loads and unloads the module on demand.
