HomeSocks Kindersicherung / Traffic Filter
ich schaffe es über den socks5 client aber leider immer jeweils nur die ping url auszulesen, daheißt youporn etc kann indexiert und ´geblockt werden, google anfragen nach porn inhalten etc aber nicht, wisst ihr da wie ich sowas noch geblockt bekommen würde ?
mein source ist in c# wenn ihr wollt pm an mich und ihr bekommt die snippets wie ich was mache
will das projekt nachher eh veröffentlichenCode:
namespace SocketServer

dns url anfrage blocken aber wie kann man den post filtern
