Hi,
I’m having a GL-AX1800, running under 4.2.1, which I want to connect to a company network using wireguard and still having issues.
One problem I have observed:
I have set an IPv6 ULA Prefix in Luci->Network->interfaces->global network options and set a subprefix in the Luci->Network->interfaces->Interface->Advanced Settings. This works for some time.
Since I am currently having issues and problems to connect the AX1800 with a router of different brand, I am changing the Wireguard settings in the GL.iNet Admin Panel repeatedly.
But when I changed the wireguard settings (pureley IPv4 at the moment), I observerd several times that the Router reset it’s IPv6 ULA Prefix (although IPv6 is not part of the wireguard configuration) to dde2:cad1:9115::/48
There’s two severe problems with that:
-
It breaks all network settings and permissions and such a lot of functionality if the router “automatically” changes the ULA Prefix without Admin’s interaction.
-
This ULA Prefix is simply wrong, not valid. Afaik this is not an assigned IPv6 range at all. IPv6 ULA addresses must be in the range fc00::/7 , which dde2:: obviously isn’t. This breaks functionality even more, since several services have access restrictions whitelisting fc00::/7 by default, which do not allow dde2:…
So two question:
Why is the router magically changing the ULA setting?
Why does it enforce an invalid IPv6 address?
