DynamicUDPIPEncap

encapsulates packets in dynamic UDP/IP headers

SYNOPSIS§

DynamicUDPIPEncap(SRC, SPORT, DST, DPORT [, CHECKSUM, INTERVAL])

Ports: 1 input, 1 output
Processing: agnostic

DESCRIPTION§

Encapsulates each incoming packet in a UDP/IP packet with source address SRC, source port SPORT, destination address DADDR, and destination port DPORT. The UDP checksum is calculated if CHECKSUM? is true; it is true by default. SPORT and DPORT are incremented by 1 every INTERVAL number of packets. By default, INTERVAL is 0, which means do not increment. This is the same element as UDPIPEncap, except for the INTERVAL functionality.

The DynamicUDPIPEncap element adds both a UDP header and an IP header.

The Strip element can be used by the receiver to get rid of the encapsulation header.

EXAMPLES§

 DynamicUDPIPEncap(1.0.0.1, 1234, 2.0.0.2, 1234, 1, 10)
