No, as I stated in the first sentence of the first post I'm using 4.2.6. 4.4 is still in beta. When it's ready for general release I'll upgrade.

Firewalls page has Force IP checked, with the default port.

Note that a fellow recently complained in the Upload/Download section that his searches have gone to hell, too.

Another factor to add into the equation, I'm filtering searches by restricting to 3 stars and cable model or better. I tried that earlier - before I changed the router configuration - and obviously saw fewer hits, but nothing like this.
