24.7 Production Series / Re: Generating a DHCPRELEASE packet

Not a solution, just a potential workaround: Change (spoof) MAC of WAN interface and reload interface?

Thanks! That's actually a great workaround

On interfaces: overview there is a "reload" button on the right of your WAN interface.

Mileage may vary. You may not get your expected result of a different IP.

I've tried that . As you perhaps suspected, it doesn't give me a new IP. Digging into it a bit more, it looks like it just kills dhclient, and the FreeBSD dhclient doesn't send a DHCPRELEASE on SIGTERM, or any signal for that matter (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265929).

Does anybody know of another command line tool that would do it? Or any experience replacing the FreeBSD dhclient with the ISC one perhaps?

24.7 Production Series / Generating a DHCPRELEASE packet

« on: August 13, 2024, 03:57:45 pm »

Hi,

Sometimes I want to get a new IP address from my ISP. In order to do so, I need to send them a DHCPRELEASE packet (as otherwise they just assign me the same address). Is there a way to do this from either the Web GUI or the command line on OPNsense? (I am purely talking about IPv4 here)

Thanks,
Neil Greatorex

There's a small bug in the code that uses the same number for "active ports" and "flapping".

I've opened a PR on GitHub to fix it: https://github.com/opnsense/core/pull/6641.
