I am currently using retail version of D-LINK DIR-X3000Z. The functionality is extremely limited, but worth for the price you paid. The retail version has new UI, which I consider amateurish, and its like a FYP UI/UX project.

Network options


System options


Firewall


Currently, I am utilizing almost 70% features that comes with this router, except for DDNS since I am behind NAT44, and some other features such as UPNP, and DMZ. The downside of this router is, after solid 14 days, you need to reboot the router, memory leaks probably or suffered kernel panic. Hence I set the router to be rebooted on daily basis.
