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.

Routing packets in multiple destination networks with overlapping address spaces

At an outbound end of a tunnel from a first data network, a packet is analyzed to determine whether the packet is to be directed to a local target in the first data network or to be sent over the tunnel to a remote target in a second data network. A target address of the packet is present in both the first data network and the second data network. When the packet is to be directed to the remote target in the second 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.
