ubuntu 12.04 ipsec server problem. Help needed

edited April 2013 in Help

Hi
I follow this guide to setup IPSEC/L2TP https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_with_Ubuntu_12.04.html
However, when I set it up in Windows as a client, I cannot connect to the server. I look at syslog, it says it is listening on port 1701
But using netstat -a , port 1701 is not open. xl2tpd do show up in ps -A.
So I am very confusing where is the problem.

    What is the output of:

    sudo ipsec verify

    Try restarting them:

    sudo /etc/init.d/xl2tpd restart
    sudo /etc/init.d/ipsec restart

    Checking your system to see if IPsec got installed and started correctly:
    Version check and ipsec on-path [OK]
    Linux Openswan U2.6.37/K3.2.0-39-virtual (netkey)
    Checking for IPsec support in kernel [OK]
    SAref kernel support [N/A]
    NETKEY: Testing XFRM related proc values [OK]
    [OK]
    [OK]
    Checking that pluto is running [OK]
    Pluto listening for IKE on udp 500 [OK]
    Pluto listening for NAT-T on udp 4500 [OK]
    Checking for 'ip' command [OK]
    Checking /bin/sh is not /bin/dash [WARNING]
    Checking for 'iptables' command [OK]
    Opportunistic Encryption Support [DISABLED]

    And I have restart them multiple times.

    Yes. Log seems fine to me too. However, port 1701 is not listened.

    share your xl2tpd.conf and ipsec.conf files

    I didn't get on with L2TP/IPSec in Ubuntu. Much more straightforward in CentOS using the many guides around. The only way I could easily get L2TP/IPSec to work in Ubuntu was with SoftEther - search it in LET, @lincoln made a step-by-step guide at http://linc01n.github.com/blog/2013/03/19/softether-on-vps/

    @dnwk i got it working with debian fine though

    @mark softether is different, although it got l2tp but it's different. I don't think there's any problem in ubuntu and L2TP over IPSec

    Sure you're not firewalling it?
