using iptables to give upload priority to slingbox (port 5001)

I have gentoo linux installed and i'm using my linux box as my home router. i have slingbox with is a tv2ip box connected as well. my father uses it to watch my country's television from Bulgaria. how can i use iptables or tc to give the highest priority of internet bandwidth to the slingbox so if my father is connected he won't have interruptions because i'm downloading with torrents on the other machine.

In my limited experience with this area, I have had moderate success using tc to set up 'Qdiscs' (Queuing Disciplines) which can accomplish what you want to do. A warning though: easy-to-use documentation or tutorials seems pretty scarce, so it probably will take you a fair bit of fiddling around if you choose to try doing this.
I configured mine using the HTB method (Hiararchical Token Bucket). It isn't perfect; I am still kinda fiddling with it on and off, but it does seem to help us share a really slooooow 28.8K dialup connection here if we are both browsing or downloading at the same time, though as you can imagine, dividing 28.8K between 2 or 3 machines is almost futile

There are kernel configurations you will need to configure when building your kernel, in the Netfilter and/or similar kernel config areas, for HTB and a large selection of other Queuing Disciplines and associated things for doing traffic-prioritizing.

Definitely use Google. Look up 'Linux Qdiscs' and similar. Also read the tc man page.

Surely there are (many?) other methods, hopefully easier or more well-documented, of doing what you want. But I don't know what they are. Maybe someone else can offer another suggestion.

Good luck!
