2.4.x is in maintenance mode, but 2.6.x unfortunately has a bug when
used with leftprotoport/rightprotoport, which is required for L2TP based
vpn connections. Only use 2.4.x if you plan to use those.

If you use openswan 2.6.x, you should NOT apply the nat-t patch to
kernels >= 2.6.23
If you use openswan 2.4.x, then the KLIPS patch might take some manual
patch work to get going. We have not updated 2.4.x to work with the
latest linux kernels. But you can look at the simiar code in 2.6.x to
figure out what's wrong with the 2.4.x. code.
