If anyone knows

The personal firewall called zonealarm has the option to "stop all internet access" ...

Now my question is...how did they go about doing this?
do they close all ports so no information can get out/in?
or is there a main port that all internet traffic goes through?

Also is this even possible through vb? or would it be a better idea in c++?


Thanks.

It should be possible...what they probably do is close down port 139 and other main ports to close off trafic. You would have to use some advanced functions with winsock and basicly build a firewall. For examples try searching these site:

I'm pretty sure ZoneAlarm when put to 'locked' mode locks all the ports and stops all incoming and outgoing data. I had several VB winsock programs running, all on different ports (1000, 1001, 1003, and some other random ones) and ZoneAlarm picked them all up when I locked it.
