IPV6 macos intermittent packet loss

[ech1965]

I’d keep the RA on in the setting and instead worked with the raw rules of the IPv6 firewall to drop all ICMPv6 (which includes RAs) coming via interfaces where IPv6 is not desirable.

One notable use case for having RAs in home network is IoT and the Thread protocol, it uses RAs. Apple TV does that when configured as a home hub.

Tried

print
                  disable-ipv6: no
                       forward: yes
              accept-redirects: yes-if-forwarding-disabled
  accept-router-advertisements: yes
          max-neighbor-entries: 8192

and

admin@rb-00] /ipv6/firewall/raw> print
Flags: X - disabled, I - invalid; D - dynamic
 0 X  chain=prerouting action=drop in-interface=VDSL log=yes protocol=icmpv6

( of course enabled)
But il looks like the rule block icmpv6 coming on both the VDSL interface ( vlan interface “connected” to the vdsl modem) and the icmpv6 destinated to the “pppoe” session traveling on this interface.
