Who does keep-alive when outbound is used? If it is the client, then there still must be some tweaks in the server as the non-outbound client will not send keep-alive.
Outbound puts all the client connection management burden upon the client.
yes, but in klaus' case, client does not know that it has been made outbound client.
it could still be possible to set "nat ping" flag on for such clients and let nathelper module to handle pinging.
