---------------------------------------------------------------------
I am currently having a look at this issue although due to the nature of the
ticket I am diving a bit in the deep end. [~rsivaram] , [~ijuma] [~mimaison]
would be able to give my some pointers on how to best approach this? Following
what [~dengziming] said earlier, I am currently looking at SocketServer which
seems to be core of where all of the netty connections are initialized but this
may the wrong place to do the change.
Furthermore I may be missing something but if one naively implements the
"broker disconnecting a connection when the client connects to force an IP
change" would create an infinite loop unless one one checks for a condition
(i.e. only on broker upgrade, is this possible) or maybe some other condition?

> Reporter: Matthias J. Sax
