Unstable ipv6
-
My operator provides both ipv4 and ipv6 adresses with dhcp, but ipv6 is often unstable with 20-30% packet loss. Can i use gateway monitor so it would disable ipv6 traffic and only use ipv4 when high packet loss happens?

That's a pretty close description of the functionality of the gateway monitoring
Here : System > Routing > Gateways > Edit, you could enter an IPv6 of your choice that does reply correctly en constantly to the ping requests.
Have a look at what this button hides :
where you can set up : how much, after what delay, what type of packet etc etc.
Normally, the default settings should work just fine.@helento1 said in Unstable ipv6:

IPv4 has still some years left, so no need to hit the panic button.
But prepare yourself by locating this button, as an ISP should do IPv6 as it does IPv4.
Not doing so means : example : You're paying Netflix but you can't receive their video's. My suggestion would be : stop paying ...Be ware that your upstream ISP link can transport at any time : IPv4 packets, or IPv6 packets (or some other type of packets).
If some local IPv4 device is saturating the ISP IPv4 connection completely, then IPv4 and IPv6 ICMP packets, who have a lower priority (!), will start to drop => packet loss.
Not your ISP fault.
This time : solution : pay them more ?! (or stop charging your ISP connection ^^) -
Gateway monitor wont disable ipv6 like i would like. My windows computer behind firewall still uses ipv6 as default and its very laggy because of packet loss. While ipv4 works fine.

Did you change your MTU (stock should be 1500) and are you allowing ICMPv6?

@Uglybrian How does MTU or ICMPv6 help if i want to disable ipv6? Problem is on my operator side. Ipv6 can work many days just fine and then there goes something wrong on my operator side and its broken for few hours. I would like my firewall disable ipv6 when it goes broken and enable it again when its ok. Now i must manually go to wan adapter and disable ipv6 from there and then test again later if its ok and enable it. I would like to do this automatically.
I have made a problem ticket to my operator and they are still investigating it, but havent find a solution.
