Good time of the day!
My English is not very good, excuse me if I said something wrong.
I just upgrade my dhcp 4.2.5 to 4.3.1 and have dhcpd v6 fatal exit when use
'fixed-prefix6' parameter in host section. Server starts normally and
works fine
until my Mikrotik router tries to request IPv6 address. Then dhcpd exits
with
message in log file:
Jan 13 04:47:33 home-gw dhcpd: Impossible condition at dhcpv6.c:4304.
Without fixed-prefix6 parameter all works as usual.
I can't understand where I missed something?
Here is my very simple configuration which works fine with 4.2.5:
***********************************
option domain-name "test.local";
option dhcp6.name-servers 2a02:xxxx:8::1, 2a02:xxxx:8::5;
default-lease-time 3600;
max-lease-time 7200;
ddns-update-style none;
authoritative;
allow leasequery;
shared-network test
{
subnet6 2a02:xxxx:8:1::/64
{
range6 2a02:xxxx:8:1::2 2a02:xxxx:8:1::6fff;
prefix6 2a02:xxxx:8:101:: 2a02:xxxx:8:11f:: /64;
host alexpro-book
{
hardware ethernet 3c:97:0e:2c:ee:4a;
fixed-address6 2a02:xxxx:8:1::7700;
}
host alexpro-wife
{
hardware ethernet E0:CB:4E:40:9F:55;
fixed-address6 2a02:xxxx:8:1::7711;
}
host alexpro-router
{
hardware ethernet D4:CA:6D:EE:14:C3;
fixed-address6 2a02:xxxx:8:1::9999;
###The string below causes fatal exit
fixed-prefix6 2a02:xxxx:8:100::/64;
}
}
