Trackinterface Prefix can be only 0

[dersch]

Hi,

i'm getting IPv6 via PPPOE and assign it to local LAN via TrackInterface. But the Prefix can be only 0. If i change it to ff there is no route anymore. (Pfsense 2.5.0)

Information about the Setup

As a side note. Actually there is only one LAN interface which tracks the WAN.

I just did another test with a second LAN Track Interface on WAN2.

There i used Prefix 1 and after a reboot (why is this necessary?) the second LAN also get it's IPv6 prefix.

So it seems you just can use it with increasing values. So why is this the case?
