Description

Hello,

Can the subnet overlapping check on the lan interfaces be removed if using 6rd? (See attached screenshot)
I only have one /64, and since wan_stf has 2001:2002:51e3:5443::/32 I cannot add subsetted networks to any lan interfaces, for example, 2001:2002:51e3:5443:1::/80, 2001:2002:51e3:5443:2::/80 and so on.

If I manually set the address via cli like this everything works, but it would be nice if the UI supported it as well.
ifconfig vtnet1 inet6 2001:2002:51e3:5443:1::/80
