      Hello,

      Our pfsense firewall is currently sending router advertisements onto the network for the link local address. This is causing some problems.
      Is there a way to turn off router advertisements, or ipv6 completely?

      Thank you in advance.

        Change the IPv6 config type on the interface to "none" if you want to turn off IPv6. However router advertisements are supposed to use the link local address, its best practice.

          The ipv6 configuration type is currently set to none (and have never been different) and still the network is receiving router advertisements.

            Are you sure they are coming from pfSense?

              Yes, pinged the ipv6 address and shutdown the machine. After that no replies.
              Also the arp shows the mac address of the lan interface

                Test:
                Goto [Interfaces: LAN] (IPv6 Configuration Type) and set (Static IPv6),
                Goto [Services: DHCPv6 server] (Router Advertisements) set to (Disabled),
                Goto [Interfaces: LAN] (IPv6 Configuration Type) and set (None) back.

                  System -> Advanced -> Networking -> uncheck "Allow IPv6"?

                    I tried unchecking "allow ipv6" but that didn't work.

                    I will try to set static ipv6 and disable RA in dhcpv6!

                    Thanks

                      This fixed the issue. I didn't wait long enough  :-X
