L2TPD/IPSEC can be used to replace the existing PPTP VPN system on Koozali SME Server It does not need any special software configure or run Virtually any mobile phone has L2TPD/Ipsec support
Installation for testing
config setprop pptpd status disabled sessions 0
You need my repo and the EPEL repo to test install.
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
You need at least one user on the system - for testing it can be admin.
IPRangeStart/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
On the server:
db ipsec_connections setprop L2TPD-PSK status disabled IPRangeStart 192.168.x.180 IPRangeFinish 192.168.x.200 rightsubnet 192.168.x.0/24 passwd somesecret dpdaction clear dpddelay 10 dpdtimeout 90
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 IPsec preshared key : as per passwd set above Username : admin (server user) Password : adminpassword (server user password)
You can regenerate the server templates with:
Note that this this will not stop or restart ipsec. Use ipsec-update to do this:
Stop the service
config setprop xl2tpd status disabled config setprop ipsec status disabled signal-event ipsec-update
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 :-)
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)
