we just wanted to configure an IPv6 subnet as client with the variable ipaddr. Found out that only a single IPv6 IP address is working with the variable ipaddr. With ipv6addr subnet is working, too.

Does not work:

client test { ipaddr = fd76:70:6e:1::/64

The "ipaddr" is intended to be used mainly for hostname lookups. As a result, it's not overly good at parsing raw IPv6 addresses.

secret = XXXXXXXXXXXXXXXXXXXXXXXXX }

Does work:

client test { ipaddr = fd76:70:6e:1::1

That's just an IPv6 address...

Does work:

client test { ipv6addr = fd76:70:6e:1::/64

i.e. when you force it to be IPv6, it works.

Error log message: Failed to parse IPv4 address string "fd76:70:6e:1::/64" /etc/freeradius/3.0/clients.conf[270]: Error parsing client section

Is it a bug? Tested in freeradius 3.0.12 and 3.0.16. Same behaviour.

It's a bug. I've pushed a fix for the v3.0.x, which should be in the 3.0.17 release. Alan DeKok.
