Several firewall schemes

Question

Computer networks

A laptop happens in places with unlimited Internet, where traffic is not a pity (well, at home, for example, or somewhere else).
And it happens that it is hooked through the limit gprs.

How to make it so that once - and the Internet is available only to ICQ and the browser.
And then just as easy to resolve everything again.

I don’t see a solution other than some kind of firewall with several working profiles.
There are such? Or some other options?

Answer 1

Comodo Firewall is basically what you need. Flexible settings, profile management + free.

Answer 2

As an option: another proxy with two types of configs

Answer 3

I just have Comodo and it's worth it.
Looked network zones.
It turns out that for each unwanted application, it is necessary to indicate in the rules that it is blocked for the “gprs” zone. Not very comfortable.
But I liked the option with configurations much more.
Created Limit and Unlimit switch via tray icon. Conveniently.
