How to enable the IPv6 firewall on your modem

Activating the IPv6 firewall in your modem's advanced settings is optional. When the firewall is activated, security on your network is enhanced, but some network functionality will be lost. 

5. Select "IPv6 Firewall" in the left sidebar.

6. Follow the steps to set up the IPv6 firewall.
 

  • Step 1:  Enable/Disable stealth mode. Do not enable stealth mode unless you fully understand the impact.

  • Step 2:  Enable the firewall.

  • Step 3:  Choose to allow/block incoming and outgoing traffic on the network.

  • Step 4:  Click "Apply" to save your changes.

About "Stealth Mode": Stealth mode prevents the router from responding to probing requests. The router will still answer incoming requests for authorized apps. Unexpected requests, such as ICMP (ping) are ignored. Do not enable Stealth Mode unless you understand the technical impacts.
