I would like to use a software to control which program may connect to the internet. I know that this behaviour is associated with the word "firewall", but some Linux users are very upset if somebody demands a Personal Firewall. I don't want to upset you by demand such a program.

I don't want to "secure ports" or other stuff a Personal Firewall promises on Windows. I looked into iptables but it does not fit my requirements.

I saw an excellent answer here ("How to block internet access for wine applications") but it's very uncomfortable to set this up.

Is there a software that asks for each program if it may access the internet?
