Hi all,

i want to create l2tp tunnel between two ubuntu machines, but most of the documents come only for l2tp over ipsec . i want only l2tp tunnel no ipsec needed. please help configure it.

thank you very much.

"OpenL2TP can be used with or without IPSec. To use IPSec, make sure
that racoon is installed (from http://ipsec-tools.sourceforge.net) and
start openl2tpd with -p ipsec.so to use the IPSec plugin. This plugin
tracks L2TP tunnel setups and installs rules in the IPSec Security Pol-
icy Database (SPD). Since this plugin tracks ephemeral port usage,
OpenL2TP supports multiple L2TP/IPSec connections between the same IP
peers. This allows configurations where there are multiple L2TP/IPSec
clients behind a NAT gateway, connecting to a remote L2TP server."

I assume many l2tp implementations can but they now assume you want ipsec also.
