Re: what does this mean?

Re: what does this mean?

From the details of the logs, it is very clear that the only transform set that is agreed is "Encryption=3DES and Hash=MD5". (See transform 10 and 12) but it is saying that the policy didn't allow to establish the IKE SA. So you can just configure this basic transform set and try creating the IKE tunnel.
