Hello list,


Apologies if this has been discussed already but I searched the web
and the mailing lists and haven't found hints on my problem.

I've got a jail, I assign it a set of IP addresses, and it just won't
take the IP6 I give it.


Uname:
FreeBSD 7.2-STABLE


Sysctl jail MIBs:
security.jail.jail_max_af_ips: 255

I fail to see what could be going wrong :(

Any pointers please ?
