WAN IPv6 gateway problem [fix]

[j-p-l]

As mentioned in the post below, my WAN IPv6 gateway was not set with Native with DHCP-PD enabled. I was able to interim fix this issue by adding a WAN-startup-script, to manually add the gateway.

#!/bin/sh
ip route add default via fe80::1 dev eth0

@RMerlin, the nvram variable "ipv6_gateway=fe80::1" was already correct, but the route is not set. Maybe there is a possible fix, to set the default gateway without setting a custom startup script?

IPv6 is not working as expected. LAN traffic okay, but no WAN connection. This is not completely new to me - have it since a couple of versions, but it did work - but not fixed in current release. Is this an asuswrt (Merlin) issue, or is it my provider (Vodafone cable Germany, static IPv4/IPv6 dual stack).

I have "Native with DHCP-PD" enabled and receive everything correctly but there is no "IPv6 WAN Gateway". Any ideas?

fe80: is a link-local IP, it's not a public/WAN IP.

This issue is very similar to mine, there are bugs in the official firmware, it's not a merlin bug,
Here I describe my issue:
