Method and system for transmitting encapsulated IPV6 data packets

A method and system for filtering data packet traffic, e.g., Internet traffic, includes the steps of: (1) receiving a data packet from the data packet traffic; (2) determining whether the data packet from the data packet traffic includes data associated with a first protocol, e.g., IPv6, encapsulated within data associated with a second protocol, e.g., IPv4; (3) removing data associated with the second protocol from the data packet if the data packet includes data associated with the first protocol encapsulated within data associated with the second protocol; and (4) transmitting the data packet including data associated with only the first protocol or the second protocol. The method and system also operate in a reverse direction, i.e., for encapsulating data packets of a first protocol within data associated with a second protocol.
