Lets look at all the fields, setting up for high priority browser traffic...
Traffic Class Name [set to anything you want]
Priority [set to high]
IP Precedence [I think you can leave this at 0]
IP Type Of Service [I think you can leave this at Normal Service]
Protocol [Leave this as TCP/UDP]
Source IP Address [Leave this blank]
Source Subnet Mask [Leave this blank]
Source Port [Leave this blank]
Destination IP Address [Leave this blank]
Destination Subnet Mask [Leave this blank]
Destination Port [You need to account for port 80 and port 8080 so type 80:8080]
I believe this will work for you as long as you are allowed to leave the fields blank that I said to leave blank. Hopefully you will not need to make a similar class for torrents, if you do then that class should be set to low priority.
Yeah, Sky are both stupid and evil and they're screwing you.
You need one of
- a bridge (as opposed to a router) that does IP QoS. That's a mess and I bet you're not going to find one for the home.
- reconfigure your Sky router to add a static route for a QoS router. I bet you can't do this; Sky apparently removed the feature from their routers a while back.
- daisy chain a second router, accept double-NAT, and break a load of network protocols. E.g. you won't be able to act as host for some online games. I strongly recommend against double-NAT, it's just going to cause more contentiousness :-).
OR probably the only practical one
- a QoS router which has been specifically designed to replace the current generation of Sky routers, and do whatever magic handshakes they're currently using to lock you out. And hope they don't change it again. This will also make support a bit of a hassle (they'll make you use the Sky router if you need to report any issue with the line).
One of the Sky modem<->router protocol is something called "MER", at least as of last year.

The ports which are used by Viber are:
You'll find instructions for configuring QoS in your router beginning on page 36 of the Linksys E3000 User's Guide which you can download from the Linksys support page, or directly from here.
