vpn site to site '/ cisco 5500 ASA failed in IKE phase 2

Hello everyone,

by creating a custom network and azure site to site connection we failed in IKE phase 2.

Our configuration:

Virtual network ip range 10.0.0.0/8, Subnet 1: 10.0.0.0/16, Subnet 2: 10.1.0.0/16, Gateway: 10.2.0.0/16

Azure Local Network: 172.29.20.0/24

we followed this articel about vpn devices for virtual networks:

Got anybody an idea?

THX! Michael Ehlert
