Virtual IP + Nat Rules = Unhappy Amazon Devices

First issue I see is that your VLAN 11 is not part of the RFC 1918 space
RFC 1918 - Address Allocation for Private Internets

10.0.0.0        -   10.255.255.255  (10/8 prefix)
172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
192.168.0.0     -   192.168.255.255 (192.168/16 prefix)

As for port forwarding on the Virtual IP for the other devices, use pftop to determine what connections that are attempting and that will help you determine what is failing.
