It depends on the types of RTR(now called Service Assurance Agent) operation.
For those RTR operation types that do not require RTR control message, e.g.,
ICMP, UDP Echo (to standard UDP echo port 7), TCP connect operation (to
wellknown TCP ports), HTTP, it should work with NAT.
For some RTR operations, e.g., jitter, it sends a control message to the
target before the actual measurement packet(to enable the RTR responder on the
target). The destination IP address is also embedded in the control message.
This won't work with NAT.
