Transmission won't allow WAN clients to use Web UI?

[moeburn]

I'm running Transmission on my WNDR3700v2, which is running Gargoyle 1.5.10.

Transmission lets me connect to its WebUI by connecting to "192.168.1.1:9091" just fine, but if I try and leave my local network, and connect to it from the WAN using my dyndns, it doesn't work. However, if I take out the ":9091" and try to connect to the Gargoyle web UI page from the WAN (which I have enabled WAN access in the Gargoyle settings), it works just fine.

So the fact that I can access the Gargoyle page from the WAN means my dyndns service is working. And the Transmission web ui is working fine if I access it from the LAN. So how do I allow access to Transmission from WAN?

EDIT: I have attached the transmission config file and the settings.json file in a rar. I'm not sure which config file Transmission is using, so I always just edit both.

Also, the bandwidth that Transmission uses shows up just fine in the "Bandwidth Usage" status page, under 'hostnames', under 'Gargoyle'. But under "B/W Distribution", if I sort by 'hostnames', it says "Gargoyle" has used exactly 0 bytes in the past 1 day, or in ANY time frame. Why can I see the current bandwidth usage for Gargoyle (aka Transmission), but not the bandwidth distribution?
