IPsec on a LAN?

[Mason Loring Bliss]

Hi there!

I'm trying to find a resource for learning how to go about setting up IPsec
on an IPv4 LAN. The Handbook and just about every resources I can find on the
'net talks about using IPsec to tunnel to another site, but I just want my
local boxes (or some subset of them) to encrypt traffic to each other.

My specific desire is to set up NFS between several local machines and have
it use an encrypted transport. It seems that IPsec is the only game in town,
and that it's very poorly documented, especially for use on a LAN as opposed
to for setting up a VPN between sites. I'd love pointers.

Thank you!
