How to set up QoS on ADSL router (terracom) for prioritizing browsing

Question

I want to configure the ADSL router which connects 10+ machines to the internet. I want to give maximum priority to browsing (ports 80,443) and set low priority for bittorrent etc.(port 42180)

I have been experimenting with settings , but with no luck. There are three settings which confuse me, along with my understanding.

1. 802.1 Priority - Related to LAN level, possible values 0-7 , higher numbers means higher priority.
2. 'Mark traffic priority' - clueless about this.
3. IPP/DS - IP Precedence - possible values 0-7 ; 6 & 7 are reserved, so set 5 for highest priority. Or when using DSCP - set 46 for highest priority.

Please help me in getting this done.

Answer 1

First of all by Qos you can only control outgoing trafic. Limiting outgoing traffic in turn may have an effect on incoming traffic on that port.

My ADSL router Qos page starts something like below

As you can see you need to provide source IP address i.e your IP address to which a priority is set(P0 is highest).

Now if you want to add new rules to Qos it goes something like below

As you can see the minimum requirement for adding a rule entry to Qos is the source IP address. Of course you can provide other configs like dest port/IP or src IP and the corresponding priority.
