Good day,

Yes, it happens regularly- it looks like it takes one hour.

I'm not using Freeswan, I'm using the KAME implementation in the 2.6 kernel,
as per my original post.

I admit that I'm not the most knowledgeable person on ipsec, but, I think
the problem might be with my setkey policy statements, since I see dynamic
policies get created upon connection that say they last one hour.  I
followed this howto exactly in that regard:

http://www.funknet.org/doc/tunnel/l2tp.html

... but I have a feeling that its setkey policy is incomplete.  SIGH.

Thanks for your reply, though!
