Generally speaking, the client with cisco needs to authorize you first.

They have to know your IP address and depending on security may even require an RSA random key to let you in. If its up to you, you merely need to configure the Cisco client at that end and authorizes your IP address.

It gets tricky if you have a dynamic IP address at your end. How can you configure the Cisco to only let you in if you changes.

I know its done, because my Dad has dynamic IP and access to his corporate network via VPN. I n that case he has an RSA card with a key that changes randomly every 15 minutes and has to type in that key when he first accesses the corporate network.

A lot of smaller organizations just have a good userid/password setup. At the Cisco side, my networking friend says its point and click with the configuration agent at the client site. To set yourself up, you or someone you designate has to be there.

AS far as the Linux side, there is a VPN client in most distributions, but you might actually need a Cisco VPN client to access Cisco VPN's. That would be available at http://www.cisco.com

Thanks Steven,
I want clear couple of points. We already have
VPN secession from IPCop to CISCO FW. We use static IP. My question is how could I come into
my work domain securily? ( then I can connect to client's site). Ofcourse, I will have a dynamic IP as I will be comming in via my ISP.
