Debian 6: IPSec-VPN?! -> Network-Manager

After changing to Debian 6 i had to recompile the Cisco IPSec kernel module (cisco_ipsec.ko). But i ended up with:
hades:/packages/vpnclient# ./vpn_install
Cisco Systems VPN Client Version 4.8.02 (0030) Linux Installer

Ok... this does not work anymore.
But the network-manager has one tab labelled vpn... What about using this one?

The first try was not successful, because the "add"-button was disabled. After some googling around there was a hint to install the following package:
apt-get install network-manager-pptp-gnome
The button was enabled but only Point-to-Point-Tunneling-Protocol could be chosen. A lookup on showed the following packages in addition:
apt-get install network-manager-openvpn-gnome
apt-get install network-manager-vpnc-gnome
After installing these packages the following vpn-types were selectable:

And with choosing vpnc the following dialog was shown

and after filling in all parameters, the vpn connection was established without any problem...
