The usual way is to assign them as /128 aliases, in which case the command to remove them would include a "/128", not "/48". I think when you're deleting a "/48" you're also removing some routes that the jail host is using. -Alan On Thu, Jul 12, 2018 at 4:30 PM, Frank de Bot (lists) wrote: > On a older server running FreeBSD 10.2 i have a number of jails.
