Hi all,
I'm switching from dhcpcd to dhcp6leased. After switching, I ran into the
problem that my externally facing interface did not get a public IPv6
address. It only had a link-local address, through which dhcp6leased
apparently was able to get a /56 from my ISP and configure the internally
facing interfaces correctly. Nothing could reach the IPv6 outside world
however.
dhcp6leased.conf was as follows:
request rapid commit
request prefix delegation on em1 for { em0 vlan4 wg0 vlan5 vlan3 }
hostname.em1 is as follows:
inet autoconf
inet6 autoconf
slaacd seems to be running just fine (but it looks like it only configures
a link-local address):
# slaacctl show interface
em1:
index: 2 running: yes temporary: yes
lladdr: 80:ee:73:f1:11:c2
inet6: fe80::82ee:73ff:fef1:11c2%em1

Back when using dhcpcd, hostname.em1 just contained a single line
"autoconf". dhcpcd was able to get a /128 using router solicitations,
configure that address on the external interface, and then get a prefix to
configure the other interfaces:
interface em1
ipv6rs
ia_na 1
ia_pd 2 em0/1 vlan4/2 wg0/3 vlan5/4 vlan3/5
The /128 was in a way different range than the prefix.
I was able to get things working with dhcp6leased by assigning an address
from the prefix itself the external interface, like so (note that em1
appears both in the "on" and the "for" part):
request prefix delegation on em1 for { em1/128 em0 vlan4 wg0 vlan5 vlan3 }
This doesn't feel right though, but I'm not sure why. I don't know why em1
doesn't get a public IPv6 address from slaacd.
Should the external interface get an external IPv6 address from slaacd
using router solicitations, and if so, what am I doing wrong here?
