Could you show us what your ISP told you?
Your computer has an IP 192.168.0.XXX.
The inside IP address of your router is 192.168.0.1, the outside IP address is one your ISP gave it
Outside calls from your computer to your bittorrent are send to 192.168.0.1, your router, your router will pass them through.
The replies from your bittorrent are sent to the outside IP address of your router, the router on its turn passes it on to your computer with the 192 IP. As you see in the router IP addresses are switched.
In the port forwarding table in router you must set port 52499 on the outside to the inside port and IP of your download app on your computer, i think for UDP
The problem is that your computer gets it IP address on power-up from the router and that it may vary, but in the port forwarding table you must specify a fixed static IP. The way out is to define in the network adapter settings of your computer a fixed, static IP for your computer, something in the range from 192.168.0.2 to say 192.168.0.200, but NOT 192.168.0.1 because that one is used by the router itself.
Hope it helps
