Title: OPNsense IPv4 only -
Post by: jimcease on October 10, 2024, 01:55:20 PM
Good morning,
I have a question.  Is there a way to turn off IPv6?  Each interface is set to none for IPv6.  I dont see an option in Advanced to turn off Ipv6.  Is there a file(s) that can be modified to turn off IPv6?  Thanks in advance for your input.

Jim

The best you can do is block most IPv6 by toggling the setting for it, which mostly pertains to firewall rules but also a few interface configuration subroutines.


Cheers,
Franco

Under Interfaces: Settings uncheck "Allow IPv6"

May I ask why IPv6 should be disabled?
