Block WINE Applications From The Internet

I have created an importable Windows Registry key that will essentially block internet access for apps run by Wine. I found the usual method of creating IPTables (for Linux) rules per process and/or per user (think: # useradd wine) extremely tedious when administering several boxen.

Import the following key using Wines Regedit:

1
2
3
4
5
6
7
8
9
10
REGEDIT4
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"MigrateProxy"=dword:00000001
"ProxyEnable"=dword:00000001
"ProxyHttp.1.1"=dword:00000000
"ProxyOverride"="<local>"
"ProxyServer"="http://NonExistantProxyAddress:80"
"User Agent"="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1"

.. and restart the app for the changes to take effect.
