How to block Application in Wireless Router, d'link dir 615 (FIRMWARE 7.09)

Hello Forumers,

Any idea of blocking a particular application to access internet?

I was trying with my Wireless Router d'link dir 615 with firmware 7.09.
But it does not come with application rules in this firmware.

I wanted to block :

1. Steam - Dota 2
2. HON
3. LOL

Thank you ! Please give some ideas
