[c-nsp] show crypto session still showing DOWN / no result for show crypto isakmp sa

[Nick Cutting]

debug crypto isakmp

shut the outside interface - then bring it back up
you should see some clues in here, the router debugs are more meaningful than ASA one's ever were.

also - Try it without NAT first, as this is a LAB
