Abstract
Systems and methods for connecting a network using one network protocol with a network using another network protocol are provided. According to an embodiment, a method is provided for performing network address translation. A data packet is received, by a protocol bridge connecting a first network, using a first protocol, and a second network, using a second protocol, via a first session of the first protocol from a first network appliance of the first network. The first protocol may be either Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6) and the second protocol is the other. The data packet is translated into the second protocol. The translation is performed in a kernel space of the protocol bridge. Finally, the data packet is transmitted via a second session of the second protocol to a second network appliance of the second network.
