k) Click on “IPsec Settings”.
l) Check the box “Use pre-shared key for authentication”, type in the pre-shared key that you created in Step 7 and then click “OK”.
m) Select the “Networking” tab on top and then select “L2TP IPSec VPN” from “Type of VPN” drop-down menu.
n) Highlight “Internet Protocol (TCP/IP)” from the list below and click on “Properties”.
o) Click the “Advanced” button on the lower side of the window.
p) In “General” tab uncheck “Use default gateway on remote network”.
q) Click OK.
r) Click OK again.
s) Click OK again to finish configuring the VPN client.
t) Type in the username and password given by your administrator and then click “Connect” to establish a VPN session.
The window should say “Verifying username and password” and then it should get minimized into the tray, just like when a modem connection is established. Try to ping some local servers to see if the connection is working.
If you are running an earlier version of Windows XP (either original XP or with SP1), you will either have to install SP2 or download a NAT patch (818043) from Windows Update.
That’s it! You are finally done! Congratulations :-)

Simple reporting for the L2TPD/IPSEC VPN Server
1. place the following script in your /etc/cron.hourly directory
#————————————————————————-
#!/bin/sh
# retrieve date in 3 letter form and assign the value to DTNOW
DTNOW=`date`
# retrieve date in 3 letter form and assign the value to P1
P1=`date +%b`
# retrieve day of the month in leading space removed format and assign it to P2
P2=`date +%e`
# retrieve Hour in 24 format and assign it to P3
P3=`date +%H`
# retrieve the integer value of P3 and decrement it by one because
# the script is run hourly and searches for the last hour access
P4=`expr $P3 - 1`
# Create a file in the /tmp directory
# a randomly named file
echo > /tmp/k30fsf98.log
echo -e “VPN Connections made from $P4:00 to $P3:00 on $DTNOW and closed\r\n”>> /tmp/k30fsf98.log
echo -e “Total Number of Connections: \r\n” >> /tmp/k30fsf98.log
grep “$P1 $P2 $P4″ /var/log/messages | grep “name = ” | grep Response | wc -l >> /tmp/k30fsf98.log
echo -e “Connection details: \r\n” >> /tmp/k30fsf98.log
grep “$P1 $P2 $P4″ /var/log/messages | grep “name = ” | grep Response >> /tmp/k30fsf98.log
echo -e “\r\n” >> /tmp/k30fsf98.log
grep “$P1 $P2 $P4″ /var/log/messages | grep “Connection closed” >> /tmp/k30fsf98.log
echo -e “\r\n” >> /tmp/k30fsf98.log
grep “$P1 $P2 $P4″ /var/log/messages | grep “: Connect time” >> /tmp/k30fsf98.log
cat /tmp/k30fsf98.log | mail -s “Hourly VPN log from $P4 and $P3 on $DTNOW” SOME_EMAIL@SOME_DOMAIN.COM
#—————————————————————————
2. Replace SOME_EMAIL@SOME_DOMAIN.COM with the email that is supposed to receive the hourly access report.

This is perfect but to install a VPN server in fedora core5 you do not have to patch l2tpd.
Just yum that with
yum install l2tpd
yum install Openswan
and follow the same configuration options.
Thanks
Thanks for this guide.I m able to stablish vpn connection but only one client can access the server.I have already add the client in /etc/ppp/chap-secrets.But it can’t work.How can I give permission to unlimited access(client)?
Wonderful web site, for VPN solution.
Not work whit shorewall 3.x firewall, any idea for configuring?. Read a wiki shorewall, but not a clear info for this pruposes. Help please, thanks.-
Thanx for this great howto! Building a VPN server has never been so simple. But I have a little problem getting my connections to work. I used your ipsec.conf, and only changed the relevant IP-addresses. Now every time I try to connect from some remote computer, I get an error message (in /var/log/messages) saying “cannot respond to IPsec SA request because no connection is known for [my PUBLIC ip-address]/32===[local IP of my VPN server]:17/1701…[public IP of remote computer][@Username]:17/1701″. The server then sends an encrypted notification INVALID_ID_INFORMATION to the remote computer.
What am I doing wrong? Could you please help me?
hi there,
this guide is works!
everything is going fine, but i still have a bug,
why this vpn cannot connect multiple user to server?
i mean if im logged in and my friend wants to connect too, he cant connect
im checking tail -f /var/log/secure and /var/log/mesages no indicator that my friend is rejected
although we use different user?
any one have same problem with me?
any one help me?
:’(
thanks
jhony, I ran into the same problem where %defaultroute was bombing on me when starting the service. The problem was the indentation of ipsec.conf was not showing properly within the instructions. The instructions look to be updated now.
