tak konecne zmena!
8.8.8.8 - nic, a tohle jsem zkousel uz driv, a vyvodil jsem z toho (chybne), ze to nezalezi na tom, koho forwarduju.
9.9.9.9 - nic
ODVR od cznicu - nic
1.1.1.1 - funguje!
Takze decka ted doma muzou na stranky ikea a instalovat veci z applestoru, ale stejne nejsem spokojenej..
Pro ilustraci, takhle vypada tcpdump kdyz ma bind forwardovat 8.8.8.8, zas je tam NXDOMAIN:
