Libreswan-xl2tpd

	Warning:
	This does appear to work, but I offer no guarantees on anything. I suggest you only use for testing and on a VM only

Version

Currently v0.2

About

Installation for testing

	Warning:
	Do not use on a production server.

	Note:
	Server MUST be in Server/Gateway mode for this to be enabled

	Note:
	You do NOT need PPTP enabled for this. You can go to your server manager and disable it forever and sing a thousand hallelujahs for secure communications ;-)

config setprop pptpd status disabled sessions 0

You need my repo and the EPEL repo to test install.

https://wiki.contribs.org/User:ReetP https://wiki.contribs.org/Epel

yum --enablerepo=reetp,epel install smeserver-libreswan-xl2tpd

That should bring everything in, including ipsec which is required

signal-event post-upgrade;signal-event reboot

Configuration settings

You need at least one user on the system - for testing it can be admin.

Keys

• IPRange Start/Finish
  

An IP range from your server.
Note it MUST NOT conflict with IPs issued by your DHCP server

• rightsubnet
  

The subnet of the remote / dialin network

• passwd
  

IPsec pre shared key as per db connection below.
Make it long and complicated !

• DNS
  

defaults to the SME server. Can add extra servers if required

• debug
  

defaults to disabled

Create connection

	Note:
	There can only be ONE L2TPD connection

On the server:

db ipsec_connections setprop L2TPD-PSK xl2tpd \ 
     status disabled \
     IPRangeStart 192.168.101.180 \
     IPRangeFinish 192.168.101.200  \
     rightsubnet 192.168.101.0/24 \
     passwd somesecret \
     dpdaction clear \
     dpddelay 10 \
     dpdtimeout 90

	Note:
	You CAN change some values as IPRangeStart and IPRangeFinish but you need to keep same subnet. So if you change 101 on IPRangeStart, you must change it on IPRangeFinist and rightsubnet too!

config setprop xl2tpd status enabled
config setprop ipsec status enabled
signal-event ipsec-update

You should now be able to create a connection from a device.

Connection type: L2TP/IPSec PSK
Server IP : Your server IP address
IPsec preshared key : as per passwd set above
Username : admin (or any user from your server )
Password : adminpassword (the password for the above  user)

You can regenerate the server templates with:

signal-event remoteaccess-update

Note that this this will not stop or restart ipsec. Use ipsec-update to do this:

signal-event ipsec-update

Stop the service

config setprop xl2tpd status disabled
config setprop ipsec status disabled
signal-event ipsec-update

Bugs

Currently the code is not in CVS.

You can add to the bug noted above or ask in the forums.

The contrib basically works. The complications arise when you want to combine it with standard host-host ipsec connections.

The code probably needs reviewing and cleaning up by a greater mind than mine :-)

ToDo

Create a 'VPN access' group or somesuch and add users to a group - I think this this could be accommodated in the contrib at a later date.

Add server manager panel (with an IPsec panel too)
