10.5: Restore Cisco VPN settings after 10.5 install Apps
This is a big deal folks. There was lots of speculation and no real definitive word as to whether Cisco's VPN client will or would work with 10.5.

Well, I can tell you right now that I installed 4.9.01 right after my (clean) install of Leopard, and it works great. If you don't want to have to configure it once you've installed it, make a backup copy of the configuration folders, and then you'll be all set to overwrite the new installation's default folders.

Read on for how to copy your 10.4.x Cisco VPN configs over to 10.5.x Cisco VPN.

On a 10.4 box, in a Terminal window, do the following:
$ sudo su -
Password:
root# tar cf /tmp/etc-opt-cisco.tar /etc/opt/cisco-vpnclient
tar: Removing leading `/' from member names
root# ls -l /tmp/etc-opt-cisco.tar 
-rw-r--r--  1 root  wheel  4167680 Oct 26 14:27 /tmp/etc-opt-cisco.tar
root# exit
logout
$ cp /tmp/etc-opt-cisco.tar $HOME
So now, in your $HOME folder, you have a .tar file with all your Cisco configs. Copy this file to a USB drive or other place so that the OSX 10.5 install doesn't overwrite it.

Install 10.5, then install Cisco VPN 4.9.01, and copy the .tar file onto your 10.5 desktop. Open up a new shell on your shiny new 10.5 box, and do this:
$ sudo su -
Password:
root# cd /etc/opt/cisco-vpnclient
root# tar xf /Users/YOURNAME/Desktop/etc-opt-cisco.tar 
root# exit
$ logout
This will extract the tar file into the right place. Now, fire up the Cisco VPN client and you will see your previously-configured entries -- hooray! Don't hestitate to contact me or post a comment if you have any issues.

Cisco VPN + Jumbo Frames = System crash (panic)

I've verified this with 4.9.01.0080 on 10.5.0.

This also is the case with OS X 10.4.10.

It'll work for a while, but the crash *will* eventually come.

When I installed 4.9.0.1 it simply recognized and used my old VPN settings. (This of course will only work if you upgraded / migrated an old Tiger user account with Cisco VPN configured).

Has anyone figured out a way to connect to a cisco VPN server using the OS's built in VPN client? I feel like I've tried everything and it always rejects me.

It simply just works for me with the Cisco Concentrator 3000 series at work.
The server needs to be configured to support plain L2TP over IPSec clients, though...
There is also a known issue that clients get kicked out every 45 mins, or so.

Is it because you 1) want to have menu bar access and 2) don't want to enter your password every time? Then use Shimo - it is amazing.

Works great under 10.4 and 10.5 and has growl notifications, too.

The cisco vpn client will add some 56 bytes of IPSec overhead to packets traversing the vpn - if the packet was sufficiently large (circa 1500 bytes) to begin with, then the ipsec overhead will take the packet size over the MTU value. Try changing mtu to 1440 bytes in system preferences > Network > Advanced.

Thanks for posting this the day AFTER I did an erase/install :-)
Actually, since I only have one config, it wasn't a big deal, but it's nice to know regardless.

What I do is mount the Cisco VPNClient installation dmg file, and copy my PCF files into the Profiles folder at the top level of the disk.

Then when you run the installer mpkg your configuration files are also installed.
