Now that the dust has settled....

I'm now a happy user of a rooted/rom'd (Candy5) Verizon LG G3 (switched from iPhone AT&T). One question I have is what firewall are people using? I would love to see a granular firewall..."allow this app to go to this site, but not that site" type firewall....so far all I see are the noroot/vpnish ones, which I don't want. Is there ANY firewall out there that can do the above? Thank you....been great so far!
