OK! That’s the point, I’ve shown only one of the config because all other are of the same kind, I’ve write about it before, sorry if I was not clear.
So when using multiple IP for jails, you can’t share one… That weird… But that’s the answer of my problems, I need to use NAT to solve that I imagine.

Here the output :
devfs_ruleset=0 nodying enforce_statfs=2 host=new ip4=new ip6=new jid=2 linux=new name=2 parent=0 path=/home/jails/front0.public.example.com nopersist securelevel=-1 allow.nochflags allow.nomount allow.mount.nodevfs allow.mount.nonullfs allow.mount.noprocfs allow.mount.nozfs allow.noquotas allow.raw_sockets allow.set_hostname allow.nosocket_af allow.sysvipc children.cur=0 children.max=0 cpuset.id=3 host.domainname="" host.hostid=0 host.hostname=front0.public.example.com host.hostuuid=00000000-0000-0000-0000-000000000000 ip4.addr=SharedIPv4,10.42.0.2 ip4.saddrsel ip6.addr=IPv6Prefix::80 ip6.saddrsel linux.osname=Linux linux.osrelease=2.6.16 linux.oss_version=198144
And here is the jails list :
STA JID IP Hostname Root Directory
--- ---- --------------- ------------------------------ ------------------------
DS N/A IPv6Prefix::2220 service0.private.example.com /home/jails/service0.private.example.com
DR 2 IPv6Prefix::80 front0.public.example.com /home/jails/front0.public.example.com
I’ve remove the gateway one to move VPN services on the host, what I read about VPN on a jails seems too much complicated.
Thanks for your help !!
