How to connect VPN server on N66U from CentOS

[woland]

Hi,
Can somebody provide me a hint on how to configure VPN client on CentOS 2.6?
The UI dialog asking for some question that i have no idea what to provide. And these fields are not optional.
The fields are:
Gateway: <it is clear, ip of my router>
Group name: <what is that? i do not have any group name in RT-N66U side. and no option to configure it>
User password: <it is clear>
Group password: <again, wtf?>
User name: <it is clear, but on some reaso it is optional. wtf?>
Thanks.

I would suggest asking in the CentOS users group or use Google.
