    fw0 down works

    Well, after trying nearly every permutation mentioned on this and other threads, taking the fw0 interface down finally solved my problem with the Cisco VPN client. Can anyone explain why this interface (and not the others) is the culprit?

    This is exactly the same thing I did to fix my problem. Worked for me as well.

    I tried every thing that has been listed in this thread and the only thing that worked for me is:

    Confirmed 4124 breaks Cisco VPN but VMWare does not

    Bottom line, installing 4124 will break most existing Cisco VPN installations. At the very least, it is a crap shoot if it will continue to work or not.

    Re-installing the Cisco software did not fix the problem in my case. I also tried the old fixes but it appears they are already in place in the /Library/StartupItems/Parallels/Parallels configuration file and it made no difference anyway. Restarting the interface also did not work, and disabling the Parallels host adapter did not work either.

    To be extra sure, I rebooted in between each install and re-install and I tried installing Parallels 4124 and then Cisco after removing both - still no joy - error 51.

    What does work flawlessly is the VMWare installation and Cisco VPN regardless of install order. Having thrown my hands up in desperation with PWS over this ongoing issue (since pre-beta2) VMWare seems to be a valid alternative for the interim.

    Works for me as well

    sudo ifconfig fw0 down

    Added this to my VPN startup script (as instructed above) and now it works great.

    Here's what I did....


    . /etc/rc.common

    # No arguemnts, print usage
    case $# in
    echo "Usage: $0 {start|stop|restart}"
    exit 1


    StartService ()
    sudo ifconfig fw0 down
    if [ -d $CISCO_VPN_DIR ]; then
    ConsoleMessage "Starting Cisco Systems VPN Driver"
    kextload $CISCO_VPN_DIR

    StopService ()
    if [ -d $CISCO_VPN_DIR ]; then
    ConsoleMessage "Stopping Cisco Systems VPN Driver"
    kextunload $CISCO_VPN_DIR

    RestartService () { StopService; StartService; }

    # Load the VPN Driver here

    if [ -f /var/run/resolv.conf.vpnbackup ]; then
    mv /var/run/resolv.conf.vpnbackup /var/run/resolv.conf

    # OS X 10.2 has /etc/rc.common:RunService() for this, but 10.1 does not
    case $1 in
    start) StartService ;;
    stop) StopService ;;
    restart) RestartService ;;
    *) echo "Usage: $0 {start|stop|restart}" ;;

    I have same problem. I can connect for few sec than I get that my connection was terminated locally. Any ideas? I am on version 3 Parallels

    same issue here. Bringing down fw0 and adding the required line to the vpn_startup script fixes the issue for me.

    My Cisco VPN Works Again!

    Version 4124 broke my Cisco VPN too. Thanks to SPUD (post #34) who found the FW0 problem and Barber199 (post #37) who provided the entry for the Cisco VPN startup script, all is well again!

    I've downloaded the update version 4128 but can't find what's changed from 4124. Does anybody know if it stops breaking the Cisco VPN client?

    I have 4128 running, along with (0030) in OS X, and now I can get to hosts inside the VPN from within the XP VM. Pretty cool. No need for a VPN client in the VM, as the OS X side now supplies VPN functionality to the VM. Didn't used to be able to do this.
