Identify download using port 80

RouterOS General
1

Does anybody experience how to differentiate download using port 80 and normal web browsing ?
I would like to set low priority if any download session using port 80.
Thanks :unamused:

and can you explain what is the difference between browsing and download? ‘browsing’ actually means downloading the files, and displaying them in your browser. first you have to decide what you want to do

I suppose what you want is to make long http downloads slower and “normal” websurfing (web browser) quick?

As - like Normunds said - there’s no technical difference between the two, the only thing you could do is use the bursting feature. Using that (you’ll find several examples for it here in the forum) you could make short http connections (like when surfing) get more bandwidth than longer ones (i.e. downloads).
To be exact, downloads would start as fast as normal surfing, but after 10 seconds (or what you configure) they would slow down to the “download-bandwidth” you configure using the bursting feature.

Hope that helps.

Alternative way to accomplish filtering using ‘connection-bytes’ (look at the firewall documentation for description).

Hi Chris,

I have tested the scenario using burst-threshold & burst-time and it works! Thanks for the reccomendation.

Another next scenario in mind, assume i have many users and i would like to provide every users with:

  1. Limit At = 16k
  2. Max Limit = 64k

I would like to set a global policy, if any of these user downloading using port 80 or FTP, then all of the download session will fall into a pool of 128kbps bandwidth (and all of them will compete) and i would like to set them to lowest priority.

Assume user1, only get 20k in the download pool and the still have remaining 44k remaining (64k-20k), then he can use the remaining bandwidth for browsing, email, or other than the download session.

A bit complecated, hope someone can help…

Sorry, I found it seconds later in the manual… it was just “hidden” from WinBox :blush:
