jails No way to jail wine or even run as a different user?

[loveydovey]

I am trying to limit wine's network connectivity. Jailing it isn't working, so I tried the simplest approach - run wine under a different group via newgrp (hoping to block wine's internet access via PF group block), but it won't launch under a different group. It launches fine normally, but the moment I change group (or use sudo to switch user), it doesn't launch.

Does anyone know if a viable approach?

i tried with telnet (i don't have wine) and it works
i did this. chgrp nogroup /usr/bin/telnet; chmod g+s /usr/bin/telnet;ipfw add 1 reset tcp from me to any gid nogroup
