Proper method to disable IPv6 on LEDE


#1

What is the proper method to disable IPv6 for all interfaces on LEDE?
Thus far I did:

Interfaces>WAN6 and unchecked "bring up on boot." What else is required?


#2

If you know how to compile your own custom image.
There is an option in menuconfig to disable ipv6 entirely for all packages.


#3

I personally unchecked all references to IPv6 and deleted WAN6.


#4

I'm not sure what remaining IPv6 you'd see (or concerns you), but:

  • Disabling WAN6 should stop native IPv6 Internet from your ISP on WAN
  • You can remove the ULA prefix from the Interfaces page
  • Remove the IPv6 address and prefix from all interfaces
  • Disable RA/DHCPv6 on all Interfaces
  • You can also disable IPv6 routing in sysctrl.conf
