Oops!!!
Been working too much, lately.
Sorry for overlooking this section and posting some noise.



    Let's get to my problem now:
    _ at boot, my re0 interface is configured with IP 192.168.0.1, along
    with an alias (192.168.0.2);
    _ my ipfw rules get loaded, issuing a "nat 2 config ip 192.168.0.1"
    command;
    _ after that ezjail is started, featuring a jail on 192.168.0.3.
    From this point on, my aliased packets go out with 192.168.0.3 as
    source address. I have to manually run "ipfw nat 2 config ip
    192.168.0.1" again, in order to have them correctly going with the
    desired IP.


​What's the ipfw command that's run at boot time?  Sounds like it's
configured to use the interface address instead of a specific IP address.​

Yes and no: it uses both, i.e. "ipfw nat 2 config if re0 ip 192.168.0.1".
However, later only the interface is listed from the show command; i.e.:

# ipfw nat 2 show config
ipfw nat 2 config if re0

Guess I'll have to use the "ip", not "if" then.



 bye & Thanks
