PfSense: Cannot save changes to LAN Interface – getting error
**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.
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.

::1 |
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.
I can verify this work around does indeed work. I did however have an issue where I lost internet on the LAN after making the changes. I had to login to pfSense through a device on a different interface to finish making the changes, then rebooted pfSense. After that the LAN had internet again. I’m guessing it would be a good idea to make all of the changes above from a device not connected to the LAN interface.
