Forcing source IP of an authenticated user's concurrent connections to be the same

[Junho Ryu <jayr0729@xxxxxxxxxxx>]

Hello,
When an authenticated user has multiple connections at the same time, I need to make sure that concurrent connections are from the same IP.
However, as long as source IP of concurrent connections are the same, I don't want to limit IP address from where connections are from.
Is it configurable?
Thanks,Jay
