Title: Howto setup IPv6 Multi WAN (Failover) with home internet
Post by: DavidRdx on April 04, 2018, 08:13:21 pm

I'm trying to setup Multi WAN IPv6 network.
I want to have it setup as failover if one internet line goes down the other one takes it over.

Currently couldn't find any solution that was working, I don't got static IPv6 addresses.

I was able to setup Multi WAN IPv6 Gateway group but there it ends.
I get from provider1 /128 WAN address and the other provider a /64 .

Are these static IP's?

Not sure how you are going to route to a /128 address on the WAN...

From a web search, which interestingly brings up a pfSense document, and that will do, let then write the docs I say...

we see this:

To setup Multi-WAN for IPv6 the following items are needed:

Two WANs, and IPv6 connectivity setup on both.
Gateways added to System > Routing for both, and confirmed connectivity on both.
LAN using a static routed /64 or similar
A routed /64 or larger block available on both WANs

So it's back to my first comment,  with your /128 WAN did the ISP give you a prefix delegation for the LAN?

I got LAN prefix for /64 Provider but not for the /128 its not static IPv6

Then unless someone else knows better, I would say it won't be possible, especially with non-static addresses.
