Hi!
"nodeip" must be static and it plays a role only if you have added one CBSD node to the other node ( via cbsd node mode=add ... )
in other cases (eg, local jails management) it is not essential.
So, if your jail have private (rfc1918) IP, but your laptop often gets a new address, all you have to do - is to enter a new IP address of node for NAT - rules forming and apply automatically:
This is two commands:
% cbsd natcfg ( enter new IP )
% cbsd naton
Do I understand correctly that you're talking about the last example - you work only with local jail (and jails have private IP). And you want to IP NAT was taked from specified interface automatically, instead of fixed/hardcoded IP?
from cbsd.
Yes, you have correctly understood my issue. Using 'natcfg' and 'naton', I will make a script to set the natip from my DHCP assigned IP automatically. Or maybe I will just rewrite /usr/jails/etc/ipfw.conf to use 'to me' syntax.
Thanks.

it seems easy to implement: olevole@09c4a25
natcfg can now be not only IPv4 but also as network interface (re0, vtnet0, ..).
The algorithm in this case is simple - on naton stage, first IPv4 was taken on the interface as natip ( This means that the IP must be initialized before CBSD starting)
At this point I'm assuming that a dynamic IP does not change during ONE system boot.
In other words, if you move the running laptop between WiFi/hotspot networks or switch ethernet cable and issued a new IP address - you'll have to run the command cbsd naton every time.
You can test new changes by swithing from port version to github CBSD-current:
- get git:
pkg install git
- remove installed version of CBSD ( it is safe for jail data):
% pkg remove cbsd
- If some files exist after removing in /usr/local/cbsd, remove it by hands:
rm -rf /usr/local/cbsd
- Clone develop-version from GH:
git clone https://github.com/olevole/cbsd.git /usr/local/cbsd
- Restore symlinks for bsdconfig module:
mkdir /usr/local/libexec/bsdconfig
ln -sf /usr/local/cbsd/share/bsdconfig/cbsd /usr/local/libexec/bsdconfig/cbsd
- Restore rc.d script via symlink:
ln -sf /usr/jails/rc.d/cbsdrsyncd /usr/local/etc/rc.d/cbsdrsyncd
ln -sf /usr/jails/rc.d/cbsdd /usr/local/etc/rc.d/cbsdd
(where /usr/jails is workdir)
- Upgrade CBSD code in your workdir from /usr/local/cbsd:
cbsd initenv
- Clean object files in /usr/local/cbsd:
make -C /usr/local/cbsd clean
from cbsd.
Thanks for taking the time to do this. I will test it tomorrow, as I am away from a computer right now. Your changes seem reasonable though.

Hi. I am trying to test this on a fresh freebsd install without cbsd, but cannot find the cbsd executable after cloning into /usr/local/cbsd and running 'make' with the required dependencies.
from cbsd.
For fresh install you need repeat steps with initenv:
% env workdir="/usr/jails" /usr/local/cbsd/sudoexec/initenv
See: http://www.bsdstore.ru/en/installing_cbsd.html#preparing ( 1b) Installing experimental (development) version of CBSD from github )
from cbsd.
Yes sorry only just noticed the docs. Tested it and new nat feature works fine from bootup. Good work.
from cbsd.
Excellent! I'll take it in the CBSD 10.3.0 release ( waiting for FreeBSD 10.3-RELEASE )
from cbsd.
