Adding an IP address to a Running Jail

[Dean E. Weimer]

I already have multiple IPs on our reverse proxy server which is running
on a FreeBSD jail, and I know how to add them to the configuration. I am
working on a new project, and need to add another IP. I have it in the
configuration, but what I can't seem to figure out how to add the IP to
the jail without restarting it.

So I am stuck until our maintenance window to complete the project,
unless someone out there can tell me how to do it if its even possible.
Of course I have other things that need done, and this project doesn't
have to be completed today, just thought it would be nice to know going
forward.

I found my own answer, I did some searching and found the -m option for
the jail command, and was able to add an IP to a jail on my test system.
Think I am still going to wait on the production system and restart it,
as I put a typo in the first time and dropped its original IP off on the
test system. But now I know going forward if I have an urgent reason it
can be done.
