Cisco vpnclient with kernel 2.6.4

[Gokul Poduval <gokul.poduval@newgsystem.com>]

Hello,
  I am using sid, and the cisco vpnclient works for me with 2.4.25. 
however with 2.6.4, the module is able to compile, and i can negotiate 
the connection succesfully. however, i cannot surf the web after that. 
has anybody managed to get vpnclient working with any 2.6 series kernel

 ( i could have tried vpnc, but the network has a group password, which 
i only have in scrambled form :( )
