Can anyone explain why this interface (and not the others) is the culprit?

Step #5 - reinstall Parallels
Step #6 - reinstall the Cisco VPN client
Step #7 - restart your machine

The order of these steps is critical.

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:

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....

#!/bin/sh

. /etc/rc.common

case $# in
0)
echo "Usage: $0 {start|stop|restart}"
exit 1
;;
esac

CISCO_VPN_DIR=/System/Library/Extensions/CiscoVPN.kext

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

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

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
fi

# 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}" ;;

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? Thanks.

iduff Senior Member Join: Jan 2007 Posts: 130	I have 4128 running, along with 4.9.0.1 (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.
