When the mirror flag is enabled in the siprouter and diameterrouter profiles, outgoing per-client create connection will be usable by any client connection from the same IP address.
In the siprouter and diameterrouter profiles, enabling mirroring incorrectly enables the internal ignore_peer_port flag, which causes the router to not consider the remote port of the client side connection when determining which of an outgoing per-client connection can be used for forwarding messages.
This occurs when the mirror flag is enabled in the siprouter and diameterrouter profiles.
The ignore_peer_port flag is no longer affected by the setting of the mirror flag, which is correct functionality.
