Ipsec between two big-ip problem, need help!

Hello guys, we need your help. We followed this documentation https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-implementations-11-4-0/18.html but it didnt help.

we are using: Point A: big-ip 4000 (11.4) in high availability Point B: big-ip 2000 (11.6)

We followed the steps, even made 3 forwarding virtual servers, 1 for incoming 1 for outgoing and 1 for SNAT. logs show that it's ipsec is not up.

Can you send us your personal documentation on how you did yours? or anything that can help us. Thanks!
