Hi, I was wondering if anyone knows anything like that program but then that works for Ubuntu? I read somewhere in a thread here on the forum, that Vpnetmon would work with Linux, but I've tried to run it through Wine. However, unfortunately without much success. The program does not start, the load somewhat, but it is never something that started when I click start and through Wine. What I'm looking for is, therefore, some form of solution when a PPTP connection is broken so that programs such as P2P stops sending / downloading data packet. Someone who has a possible solution to this? There are two firewalls that are available in the Applications Centre, but no one there for you single application can set the IP addresses who is allowed to use this particular program. Will a similar Comodo for Windows. But this I have not found a similar program for Ubuntu. Thanks.
