Description

I installes FreeNAS 11.2RC1 from scratch. Installed nextcloud plugin. Enabled IPv6 AutoConfiguration but I do not get an IPv6 adress for the Jail NIC.
The host does have an IPv6, so SLAAC is working in the network.

Christian: You have manually edited your rc.conf and have some bad entries. Remove those and your problem will be solved.

This:

ifconfig_epair0b="DHCP" 
host_hostname="nextcloud" 
cron_flags="$cron_flags -J 15" 

# Disable Sendmail by default
sendmail_enable="NONE" 
sendmail_submit_enable="NO" 
sendmail_outbound_enable="NO" 
sendmail_msp_queue_enable="NO" 

# Run secure syslog
syslogd_flags="-c -ss" 

# Enable IPv6
ifconfig_epair0b="DHCP" 
# ipv6_activate_all_interfaces="YES" 
nginx_enable="YES" 
mysql_enable="YES" 
php_fpm_enable="YES" 
# rtsold_enable="YES" 
rtsold_enable="YES" 
ifconfig_epair0b="DHCP" 

Should become:

ifconfig_epair0b="DHCP" 
host_hostname="nextcloud" 
cron_flags="$cron_flags -J 15" 

# Disable Sendmail by default
sendmail_enable="NONE" 
sendmail_submit_enable="NO" 
sendmail_outbound_enable="NO" 
sendmail_msp_queue_enable="NO" 

# Run secure syslog
syslogd_flags="-c -ss" 

# Enable IPv6
ipv6_activate_all_interfaces="YES" 
nginx_enable="YES" 
mysql_enable="YES" 
php_fpm_enable="YES" 
rtsold_enable="YES"

Hello Brandon,

thank you very much for your checking. Those changes were done trying out various things becuase the SLAAC did not work in the first place.
I reverted the changes in the jails's /etc/rc.conf to what you proposed and restarted the jail.

This is what I get now:

epair0b does not accept Router Advertisement.

#7 Updated by Christian Parg over 1 year ago

When I

  1. pull back the virtual interface from the jail to the host and
  2. enable router advertisement.
    • => It works on the host, I do get a IPv6 through SLAAC.
  3. But as soon as I push back the VNET interface to the jail
  4. => the IPv6 is gone

See this output: (I replaced parts of the IPv6 by xxx)

Looks like the epair0b Interface has IPv6 switched off when used in the Jail for some reason.
Remarkable since the lo0 interface does have a link local address at least.

When I do

ifconfig epair0b inet6 auto_linklocal accept_rtadv autoconf

in the jail it also works:

.... so why are those IPv6 flags not enabled automatically when the Jails starts ?
What layer is supposed to do this ? iocage ?
Or rather: What's disabling it ?

Thx
Christian

iocage does that exact thing when you start a jail. With all your modifications you may have caused odd behavior.

Try making sure the rc.conf is correct in your jail and restarting your host. That should allow everything to work correctly.

My apologies Christian, iocage only did part of that, I seemed to recall I did the whole thing.

PR: https://github.com/freenas/iocage/pull/85

That will now do the additional parameters. The stable PR https://github.com/freenas/iocage/pull/84 also now has this commit.

Hello Brandon,

many thanks for your investigations.

I tried to patch the iocage but w/o success until now.
Do you know when a FreeNAS update will be available that contains that fix ?

Anyway, I found a hack to workaround the issue for the time being.

Thanks

Christian

I have the same issue on an freshly installed FreeNAS-11.2-RELEASE-U1.
Created an jail, configured an static ipv4 address and set ipv6 to auto config. the jail gets no ipv6 not even link local. Host has an auto configured ipv6 so slaac is working in my network. i have not edited any files manually.

like Christian i can get ipv6 working manually inside the jail:

Syed: please create a new ticket so a dev can look at your configuration.
