++ Routing NAT between Hardware Switch Ports ++

Hey, we need to setup three test networks for testing with some new voip Mitel systems. For that I created three hardware switches on out 100D, static routes, policy routes and ipv4 policies. Port 7: 10.10.0.254/24 -> Dell Switch -> Mitel 400 HQ Port 8: 10.20.0.254/24 -> Dell Switch -> Mitel 400 Branch A Port 9: 10.30.0.254/24 -> Dell Switch -> Mitel 400 Branch B

Ping and tracert from the Mitel Phone Server "10.10.10.xx/24" to the phone systems is working as expected. But for some reason we do not get the AIN network from the Mitel working. The systems are shown as not connected. I cannot find a missing peace in the firewall config. Unfortunately I can only add one image here.
