Hi Alexander, thanks for your feedback. The concept of user was really used for quickly re-using existing sessions in NAT. With port-overloading, ports are no longer a precious resource and dropping “users” means not having to maintain an extra hash table.
To better understand your problem, can you please state your use case for dumping these sessions?
