I think that the text talking about NAT could be used in place of the
"depending on your local network setup" like "one common case where
this may happen is when there is some form of Network Address
Translation (NAT) somewhere between the client and the system being
installed".

So:

The <command>ssh</command> server in the installer uses a default
configuration that does not send keep-alive packets. In principle, a
connection to the system being installed should be kept open
indefinitely. However, in some situations &mdash; one common case
where this may happen is when there is some form of Network Address
Translation (NAT) somewhere between the client and the system being
installed &mdash; the connection may be lost after some period of
inactivity. Depending on at which point of the installation the
connection was lost, you may or may not be able to resume the
installation after reconnecting.
