Inherit is in fact an option though. It just reveals everything from the host network stack to the jail. So a daemon can bind on any IP address from the host. EG; in jail.conf; ip4 = inherit; ip6 = inherit;I'm not sure where you found the "inherit" option for IP addresses, but that's not supported in jail.conf(5); you need to provide an IP address that is assigned to some interface running on the host (perhaps an alias.)
The IP address will be one that you've already assigned to an 'actual' network adapter, perhaps as an alias. There are a number of tools out there to make jails easier to manage; iocage and ezjail come to mind.
