Odd, I distinctly remember pasting the links into an email. Anyway,

That has nothing to do with the retransmission settings on the client.
Rather the DPD and retransmission (and rekeying) settings on the server.
So make sure the server does not terminate the SA if the client is not
reachable for longer periods of time (to clean out old SAs a DPD
interval of several hours could still be useful).
