QNAP and Transmission

Hello.

First of all, excuse me for my bad english.

I bought a new QNAP, and i can’t download fast, I only reach 54kb, but in my computer i reach 2.5mb.

Looking for internet i think I need to forward the ports : 51413 and 6881-6889, can you help me to do it?

I have a Mikrotik of course.

is the QNAP connected to the router over cable directly or over a switch? Do you have any Queue configuration in the mikrotik device?

Is connected directly to the router over cable.
