Help: Disablekan Preferred & alternate DNS server

[itachi]

Salam warga CG,

nak mintak tolong otai2 IT semua,
macam mana nak disablekan Preferred & alternate DNS server
seperti dlm gmbar ni:

Saya dah setting open DNS kat router, kasi block sumer web poron.
memang jadi. tapi bila saya tukar Preferred & alternate DNS server kt pc, web poron leh je access..
so ade sesape leh tulun?

benda ni kena setting kat pc yang connect ke router or boleh setting kat router tu sendiri? mohon pencerahan pls

*penting sebab xnak bagi adik beradik access web2 poron ni..trimass

Org nk tgk poron pakai open dns / google dns la. Kau set jd default dns balik. Tak boleh bukak la poron tu. Kau klik kt obtain dns automatically tu...

Permit source from any ke IP DNS kita nak pakai TCP/UDP
Deny source ke Any port 53 TCP/UDP

Set kat router / firewall

klik je obtain dns automatically..
tapi kalu dier connect wifi guna henset pastu guna openDNS still leh access..
kalu dier slalu bukak porn..
maknanya dia tau camna nak ejas DNS ni..
kalu dier pkai pc yg tt pkai tu block dekat hosts je..

DNS pakai port 53.

Kalau block all traffic on port 53, memang konpem tak boleh communicate dengan DNS server.

Tapi, kena la allow IP DNS tertentu, kalau tak cemana nak browsing.

dekat router, atau firewall.

Deny all traffic from any(source) to any(destination) on port 53 TCP dan UDP.

Allow all traffic from 192.168.x.x/24 (Source) to 202.188.0.133 (Destination) on port 53 TCP dan UDP

192.168.x.x/24 refer pada network kat rumah tu atau boleh juga letak IP range macam 192.168.0.1-192.168.0.20 atau boleh juga letak specific IP PC macam 192.168.0.2.

202.188.0.133 refer pada TM punya DNS
