DHCPv6 configuration: The specified range lies outside of the current subnet.
-
Hi,
This is continuing to be an issue, it was reported in 2016 (https://forum.netgate.com/topic/107113/services-dhcpv6-server-ra-lan-dhcpv6-server-range-error), there was a link to a possible fix (which does not work for me).
I have an delegated /48 which I split in multiple /64 - which give me:
Lan Addr: 2a06:4004:1234:1::1/64
The dhcpv6 then gives me:
Subnet 2a06:4004:1234:1:: /64
Range From: ::1000
Range To: ::2000When I press save I get: The specified range lies outside of the current subnet.
This has been an ongoing issue for year, and it looks like it have not yet been fixed (at least not in 2.6.0).
Is this fixed in the no-so-opensource version, or will I have to change to OpnSense (where it works) ?
Thanks.

That already looks unusual to me.

I replaced the last 4 digits of the address with 1234.
I have solved the issue - using RA stateless dhcp instead of DHCPv6 - but this have been reported more than once ... and still not fixed.
I'll give OpnSense a look as they at least do fix issues.

Sure, still looks wrong. The address should be the MAC address for the host part.

You can't just leave ::1000 and :2000
You have to set the full range.. Those are just place holders..
That range is quite large 2a06:4004:1234:1:: to 2a06:4004:1234:1:ffff:ffff:ffff:ffff
Maybe you want to hand out
2a06:4004:1234:1:42::1000 to 2a06:4004:1234:1:42:2000
so those ::1000 to ::2000 are just place holders for the actual IPs that could be handed out in your selected range. So you have to be specific on your actual range you want to use.
