How to block access to sites through a browser or router

Introduction

If you want to quickly close access to online casinos, browser extensions and router tools will help you block any channel: from direct links to backup domains. Below are specific instructions.

1. Locking in the browser

1. 1 Extensions

1. BlockSite (Chrome, Firefox):

• Install from the extension store.
• Open the settings → "Block Site" → "Add a site" → enter the casino domains (for example, '* .casino. com`, `*.bet`).
• Protect access with a password so that the lock cannot be removed.

2. LeechBlock NG (Firefox):

• Go to Add-ons → LeechBlock NG → Options.
• Create a new set → in the "Blocked URLs" field, list all URLs of casinos and offshore sites.
• Set the blocking schedule around the clock.

1. 2 Editing hosts

1. Open the hosts file:

• Windows: `C: \Windows\System32\drivers\etc\hosts`
• macOS/Linux: `/etc/hosts`
2. Add lines:
• ```
• 127. 0. 0. 1 casino. com
• 127. 0. 0. 1 www.casino. com
• 127. 0. 0. 1 bet. example. com
• ```
3. Save the file (under admin/root) and clear the DNS cache:
• Windows: `ipconfig /flushdns`
• macOS: `sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder`

2. Blocking at the router level

2. 1 DNS filters

1. OpenDNS FamilyShield:


On the router, in the WAN/DNS settings, specify:
• ```
• Primary DNS: 208. 67. 222. 123
• Secondary DNS: 208. 67. 220. 123
• ```
• Save and reboot the router.

2. CleanBrowsing Security:
• DNS: `185. 228. 168. 9` / `185. 228. 169. 9`
• Similarly - in the router settings.

2. 2 Parental controls

1. Go to the admin panel of the router (usually 192. 168. 0. 1 or 192. 168. 1. 1).
2. Go to Parental Controls or Access Restrictions.
3. Create a rule:
• Rule Name: Block Gambling
• Target devices are all or specified IP/MAC.
• Blocked Domains - Enter a list of casino URLs.
• Time: "Always."
• 4. Save and restart the device.

3. Combined solution and validation

1. Combine both levels: extensions + hosts + router.
2. Check:
• Try opening blocked addresses in different browsers and on mobile devices on your network.
• If one method does not work, other layers will connect the lock.
• 3. Password support: Store extension and router passwords with a trusted person to prevent impulsive disconnection.

Conclusion

Blocking access through the browser and router is a fast and reliable combination of technical barriers. Extensions, editing hosts and DNS filters on the router block any paths to gambling sites, and the password for the trustee excludes bypassing.
