Restricts and Limiting Video Streaming with Mikrotik

Posted by Admin Monday, June 18, 2012 1 comments
If you have a proxy server, you can restrict video streaming access using access control list or using contents filtering program such as squidGuard, DansGuardian, etc. But there are many websites with embedded video that has not been filtered yet. Mikrotik can help you overcome this problem and restrict access to embedded streaming video with ease.
  • Restrict bandwidth usage for embedded video streaming
You can use the following script to limit bandwidth usage for sites that embedding video streaming such YouTube, Metacafe, Tube8, etc. I’m personally already tested this script and works fine.
The scenario is using mikrotik built-in Layer7 Protocol to detects embedded video streaming on any websites, marking the data packets, then defining bandwidth limit using Simple Queue rule.
First, add a video content filter at Layer7 protocol:
Second, marking data packets using firewall mangle:
Then finally, add new rule in simple queue to limit bandwidth usage for http-video packets (in this example, download for embedded video streaming was capped at 64kbps, you can define this to suite your needs).
  •  Blocking embedded video streaming with mikrotik
We previously able to apply bandwidth restrictions for embedded streaming video, how about block any embedded streaming videos so clients will not able to play embedded video streaming. In this scenario, any websites that is embedding streaming video can still be accessed and browsed as usual, but when playing streaming video, it will not be in loaded at all.
This useful when implemented at the office environment, where users can browse internet, but cannot watch video streaming at all :)
The scenario is similar as above, but with a little adjustment : all embedded video streaming packets will be dropped.
First, add a video content filter at Layer7 protocol:
Second, marking data packets using firewall mangle:
Finally, drop all http-video packets :)
 Just give a try : open any video on Youtube, and see what happens. All videos should not able to loaded properly since the data packets is dropped at mikrotik firewall.

Mikrotik RouterBoard RB800 Review

Posted by Admin Friday, June 8, 2012 0 comments
Mikrotik Router Board RB800 Review - If you do a little digging, you will find the RB800, which is set to release in a few weeks. This is a 800MHZ board which makes it the most powerful wireless board to date! It seems like on most tower installations, you are bridging at the radio and routing at the base of the tower.

It looks like Mikrotik is trying to beef up the radio so much that you no longer will need to route at the base, all will be handled by a single piece of gear. I’m going to reserve judgment for some real world tests, but it looks like a pretty nice board. It looks like they will be coming in around $340 over at BalticNetworks. Perhaps they will be kind enough to send me one for review (hint hint).


800Mhz
256MB RAM
4 minipci slots
3 gigE ports
2 daughter board connections
1 minipci-e slot
1 compact flash slot
