Port forward not working for tranmissionbt Gui

[sandman06]

I have freenas v7 running with bitorrent service. The BT server runs using two different ports. one for accessing the web gui and another for allowing incoming connections.

I have also dynamic dns running so that i can resolve the ip address external without having to type the ip.
I have created a nat rule as follows to allow traffic external to my freenas server on 192.168.1.250:9091

however it does not seem to work and i cant access my webgui

pictures below.

what am i doing wrong ?

am i wright in thinking i should still be able to access the webgui via my dynamic from my own wan ip ?
