Hello Misc !
I have a strange problem, and google doesn't help me.
I want to make an IPSec+GRE tunnel with OSPF. For now, OSPF over GRE is
perfectly working (ipv4+ipv6).
I have a problem with IPSec, and I don't find how to resolve it.

It's a fresh OpenBSD 5.2 image.

The error is the following:
attribute_unacceptable: ENCRYPTION_ALGORITHM: got AES_CBC, expected
3DES_CBC 

My ipsec.conf is very simple for now:

on host A

ike esp transport from 10.0.0.1 to 10.0.0.2

and on host B

ike esp transport from 10.0.0.2 to 10.0.0.1

Any idea ?

Thanks for advance
