Whenever I try to do this, I get a slew of messages in the form:
Apr 21 15:13:41 [IKEv1]: Group = #, IP = #, Header invalid (next payload = 11)
from the ASA. The RVS4000 is equally unhelpful.
I've made sure they have appropriate Phase 1 settings, and even reset the pre-shared key to "test" to make sure it wasn't typoed.
If anyone else has tried and succeeded with this, can they give me something step-by-step on how to set this up?
