I've got a separate user for running untrusted applications in wine and it was relieved from accessing network at all by using
# iptables -A OUTPUT -p all -m owner --uid-owner username -j DROP
Now, even winecfg on a clean
WINEPREFIX is slow to start. And it's getting blazingly fast if either regain access to network or the network is down (as in
ifconfig wlan0 down).
What can I do to still restrict access to network and have the network connectivity on a different user?
