Transit vlan from Nexus to Fortigate

[st3rling]

Hello,
We have a Nexus switch 5548 connected to FortiGate 100D via regular trunk port. All intervlan routing will be done on the Nexus switch and also has a transit vlan between Nexus and Fortigate that will carry other vlans for the internet access. Right now I can access the internet from Nexus from Transit vlan 254 but unable from other vlans. What am I missing? I've attached configs from both devices.
Thank you in advance!

(sorry, couldn't figure out how to attach files directly here)
