1. A method of configuring rules in a network visibility system, said method comprising:

  • maintaining, at a network device, a default rules table, which specifies a default allocation of IP addresses to output ports;

    receiving, at the network device, control information containing, for a tunnel, an endpoint IP address of a control session and an endpoint IP address of a data session;

    determining, at the network device, whether the endpoint IP address of said control session and the endpoint IP address of said data session in said default rules table are allocated to a same output port of the network device; and

    if the endpoint IP address of said control session and the endpoint IP address of said data session are not allocated to the same output port of the network device, configuring, at the network device, a dynamic rule in a dynamic rules table to force packets of both said control session and said data session to be forwarded to the same output port of the network device.
