Hmm, it seems you configured the ports in 3 different ways
.
First disable the port triggering for bittornado under applications, we don't need that.
You have a build-in firewall, good, so we will use this to do the port forwarding. The advantage is, that you can set port ranges and on the virtual server setup you can only set single ports. As you already have entries on the firewall page, leave the first two bittornado settings enabled, but disable or remove the 5 settings with the single ports listed (6881,..,6885). I guess that they are linked from the virtual server page, if not disable or remove the settings there too.
So you should now have disabled/removed all settings from applications and virtual server screen and you should have the two entries for bittornado on the firewall screen.
Now test the settings on your first computer, check if ports are set to 6881-6940 in bittornado, also ensure that the actual IP is 192.168.0.100.
