man ssh(1):
KeepAlive
Specifies whether the system should send keepalive
messages to the other side. If they are sent,
death of the connection or crash of one of the
machines will be properly noticed. However, this
means that connections will die if the route is
down temporarily, and some people find it annoying.

The default is "yes" (to send keepalives), and the
client will notice if the network goes down or the
remote host dies. This is important in scripts,
and many users want it too.

To disable keepalives, the value should be set to
"no" in both the server and the client configura­
tion files.

Should be enough to prevent the masq port from closing...
