I am using 2.4.13 openswan in Fedora 4 system

I installed xl2tpd-1.1.12 in system


>From windows XP machine (Where I have option to set pre-shared key for
authentication under security options tab), I trying to establish L2TP Over
IPSec connection establishment.


I added pre-shared key in ipsec.secrets


Connection is established, but when I captured the packets, I can see only
l2tp packets not esp packets.


What I am assuming L2TP Over IPSec traffic is, an IP packet is encapsulated
into l2tp packet and again encapsulated into esp packet. Please correct me
know if my understanding is wrong.


I am attaching my ipsec.conf , xl2tpd.conf and console capture of xl2tpd
server during connection establishment (xl2tpd.txt) along with this mail


Please let me know if I miss anything or if I did anything wrong


Thanks in advance
