Hi Francis, A quick question: why is there a SD-CGN? Do you mean the second NAT at AFTR used to reshape the out-of-range source port into the restricted port range? If so, IMHO it is stateful, not using an algorithm. And I think it still doesn't solve the security issue. Please

The principle is good, details are not: - only switched (giga) Ethernets were used (no wireless) - the PCP should get double arrow - all SD-B4s run a PCP/NAT-PMP/UPnP-GID-v1+v2 server (in fact they have the same kind of softwares, the laptop just offers more tools, 1 times larger
