Setting a fixed IPv6 address post install?

Hi,

Is it possible to set a fixed IPv6 address post install, ie after using the system for over a year? The add address doesn’t allow you to add an IPv6 address only IPv4 addresses.

I assume the SLAC address it chooses sticks once generated? It seems to when I’ve tested it.

Ok, solved it myself. The on-computer console allows you to do it, but it seems impossible via the web interface.
