| 1. A method for sending a data packet from a source in a local area network (LAN) to a destination outside the LAN comprising
the steps of:
receiving a data packet enroute from the source in the LAN to the destination;
determining if the source in the LAN and the destination are members of a virtual private network, and if so:
determining an encryption algorithm for messages sent between members of the virtual private network by accessing a portion
of a memory that maintains information identifying various encryption algorithms to be utilized for data packets sent between
members of various virtual private networks;
determining a compression algorithm for messages sent between members of the virtual private network by accessing a portion
of the memory that maintains information identifying various compression algorithms to be utilized for data packets sent between
members of the various virtual private networks;
executing the determined encryption algorithm on at least a payload portion of the data packet;
executing the determined compression algorithm on at least the payload portion of the data packet; and
forwarding the encrypted and compressed data packet to the destination outside the LAN.
