Ok, here's the problem.....

I got one Desktop-PC(WinXP) and a Laptop(Debian Linux).

The Desktop-PC has two network-cards:

1.) a Netgear 311v2 WLan Adapter
2.) A 100 Mbit Intel Ethernet Adapter

My Laptop has 1 network card:

1.) 100 MBit Ethernet Adapter

The Ethernet adapter of my Desktop-PC is connected with the Etehrnet adapter
of my
Laptop.

The "Netgear 311v2" gives access to the Internet in two ways:

1.) a restricted Internet Access (e.g ssh is not permitted )
2.) a unrestricted Internet Access(ssh usage is possible) together with a
vpn software (Cisco VPN Client)

I configured my Dektop-PC as a Gateway , so that i can use the Internet
access on my Laptop.
Everything works fine in the case of the restricted Internet access - I can
surf on the Laptop without problems.
In order to use the unrestricted Internet access on the Laptop i installed
the "cisco vpn client for linux"
on my Laptop. When i start it, everything seems to be ok - The VPN client
establishes the connection,
outputs the connection information like , IP adress of vpn server and so on.
But when i start a application like firefox, i have no access to the
internet.
I even can't ping the vpn server to which the conection has been
established.

Some advices?

Thx in advance

Axel
