VPN IPSec Openswan
Hi all,
I have installed Openswan and configured IPSec and works perfect, but for some unknown reasons it stop working. I see that the tunnels are up and established. The route to the destination are added. Everything by the book seems to be ok. But somehow when i start to ping the other side ( private ip ) the packet for that tunnel trying to go out from the interface that have public ip. And for the other tunnel they are not going anyway. All this is on a linux machine CentOS, with eth0 - public ip address, eth0:0 and eth0:1 are private for the tunnels. Can someone help me out here because i need this thing to work ( it's a production ) and i have lost a whole week.
Thanks in advanced !

Hi Guys,
Please could you tell me if it is possible to have a single rule/filter to allow a certain port range instead of a separate rule for each port?
I'm sure it must be possible but I am unable to find the syntax.
Thanks

L2tpIPsecVpn(1) General Commands Manual L2tpIPsecVpn(1)
NAME
L2tpIPsecVpn - L2tp over IPsec VPN Manager applet for the GNOME Desktop
SYNOPSIS
L2tpIPsecVpn [options]
DESCRIPTION
This GUI is not a network manager plugin. However, it provides a systray icon in the indicator applet from which a non privileged user can
establish and bring down L2TP over IPsec VPN connections.
From there the user can add, remove and edit vpn connections.
Editing allows configuring various options for IPsec, L2TP and PPP.
Among others, the user can configure eg. the gateway, the use of either PSK or a certificate for authentication, various L2TP options as
redial- timeout and attempts and of course all important PPP options. It also allows you to configure PPP for tunnel splitting because you
can add routes as you want.
When applying your settings, all necessary configuration files are written accordingly (ipsec.conf, xl2tp.conf, options.xl2tpd, opensc.conf
up and down scripts ...).
It relies on Openswan and xl2tp packages as the underlying protocol handlers.
You can also use certificates on your local machine or, if e.g. OpenSC is installed and configured, even on a smart card to handle PPP
authentication.
The GUI automatically detects when network interfaces are going up or down and can (if so configured) automatically establish or close VPN
connections.
OPTIONS
startConnectionEditor
Starts the connection editor dialog.
applySettings
Write configuration files according to the connection settings, must be started with root privileges, ie use gksudo as non root
user.
deleteAllConfFiles
Delete all configuration files, must be started with root privileges, ie use gksudo as non root user.
