I don't think that installing a firewall, then disabling it is going to do anything

LOTR asked you to do the port 6346 test... what was your result? You gave a list of different devices, are you using them all? The MN 700 router has NAT & SPI firewalls, these are probably a big part of your problem (I can't find info on internal firewalls for the other devices).
I can't find any info on UPnP for any of those gadgets

so maybe manually port forwarding is the way to go.
Step 1. Set up a static IP address (this has to be done first)

Step 2. Port forwarding

Step 3. Set manual p/f within LW. Tools > options > advanced > firewall config. Now make sure the listening port is 6346. Tick 'manual port forward' & make sure 6346 is in this box too. Apply.
Now cross your fingers & hope it works
