Abstract
A packet is analyzed at an outbound end of a tunnel from a first data network to determine whether the packet is directed to a first remote target in a first remote data network over a first tunnel or to a second remote target in a second remote data network over a second tunnel. A target address of the packet is present in both the first remote data network and the second remote data network. When the packet is to be directed to the first remote target in the first remote data network, an octet in the target address of the packet is changed from a first value to a second value, the changing forming a modified packet. When the second value is stored in the octet, the modified packet is caused to be sent to the tunnel for delivery to the second data network.
