    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    So you're saying the VPN worked when ipsec verify showed that RSA private key is disabled? I wonder how one would configure things to disable RSA private keys... I've looked through various manpages, but all I can find is an "authby" option for ipsecd, which you've already got enabled in your configs below. I also have it disabled (really "authby=secret", which I assume disables RSA key authentication), but I'm getting
    Code:
    checking for RSA private key (/etc/ipsec.secrets) [OK]

    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    Below is my auth.log entry for when I'm trying to connect via my Iphone over 3G. I've replaced ServerName, iphone address, and Comcast IP for security. I removed the times, all the logs shown were produced within 3 seconds. I also shortened down some of the Vendor ID stuff with a ... for security.

    Right now on the iPhone I'm getting the following error message.

    Code:
    The L2TP-VPN server did not respond.  Try reconnecting.  If the problem continues, verify your settings and contact your Administrator.

    Excerpt from my auth.log on Ubuntu. Is there another log file I should be showing?

    Seems like maybe xl2tpd is the culprit, although I'm not sure why?

    I'm at work and my system is unreachable at the moment, but your logs look exactly like mine. The interesting thing, in my noob opinion, is that the LT2P tunnel looks like it opens properly and then nothing else happens.

    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    Ok, so from reading around there appears to be a bug with openswan 2.6.x that breaks xl2tp. The only fix I've seen is to roll back to 2.4.x in order to fix the problem, which worked for me originally.

    Anyone know how to roll back a single package and its dependencies?

    I've been discussing this with a few engineers who have done OpenSwan deployments before and I mentioned reading the same thing, only now I can't find any of the sites that said there are problems with 2.6.x + xl2tp. Do you have any links handy? Knowing why it breaks and seeing other people's information might help lead us to a solution here.

    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    I just tried to figure out how to downgrade to the older 2.4.9 package using apt-get and ended up deciding to install the latest 2.6.32 from http://www.openswan.org/code/ from source. I had to look in the README and install a few compilation tools using apt-get (not a huge surprise). Overall it wasn't too bad getting it to compile and install.

    Now I'm on 2.6.32 and I'm getting totally different errors (yey?!?). I'm getting a ton of this in syslog:

    Code:

    My /var/log/auth.log looks like it has the same errors as before:

    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    Bit of googling lead me here. Getting the exact same error as dsuchter.

    Tried install from both source and apt-get, seems a problem between ipsec and ppp, using conf that def works (using it on a 9.10 server).

    dsuchter are you running 10.10?

    Yup, fresh install of Ubuntu 10.10 on an Acer Aspire One AOA110 netbook (Maverick Netbook Edition) specifically so I could make a VPN endpoint in my network:

    I have the same problem I can't connect from windows7 or my iPhone to my vpn server.

    Re: Guide: Openswan, XL2TP and PPP on Ubuntu Maverick for iPhone VPN Connection

    It occurs to me to mention I'm on a Actiontec MI424WR-GEN2 hardware version "F" router supplied by Verizon for my FiOS connection. It is running firmware 20.10.7.5. Supposedly the default is to support VPN passthrough, but I don't know if inbound VPN connections would require anything above and beyond the UDP500/4500 forwards I've setup.
