A method is presented for setting up communication parameters in a virtual private network node for connecting to at least one other node in the virtual private network. The method may include reading information from a hardware token for determining how to connect to a packet data network; reading information from the hardware token for determining how to obtain configuration information for the virtual private network node; connecting to a packet data network on the basis of information read from the hardware token; obtaining configuration information for the virtual private network node on the basis of information read from the hardware token; and using obtained configuration information for setting up the communication parameters.
