Cannot save changes to LAN Interface - Getting error

tagit446 · Feb 28, 2021, 5:38 PM

The following input errors were detected:

The Router Advertisements Server is active on this interface and it can be used only with a static IPv6 configuration. Please disable the Router Advertisements Server service on this interface first, then change the interface configuration.

I am re-configuring my network and need to change the LAN interfaces IP and description but it will not let me save any changes. IPv6 is turned off everywhere that I am aware of.

Could this be a bug in v2.5?

Any work around that will allow me to make my needed changes?

Missed this in my initial post but after doing another search I came across this:

1. Temporarily enable IPv6 on your LAN interface and set IPv6 Configuration Type to "Static IPv6", then assign it an IPv6 address ("::1" without quotes works with mask /128). Then Save.
2. Go to Services/DHCPv6 Server & RA/LAN/Router Advertisements then set Router Mode to "Disabled". Then Save.
3. Go back to the LAN interface and set IPv6 Configuration Type back to "None" then Save.

Seems to have worked and I can now make changes to the LAN interface.
