Next step testing #IPv6only operation in my local network, I wanted to give #dhcp "option 108" (IPv6-only preferred) a try.
I'm running #ISC #dhcpd on my #FreeBSD router/firewall, so I looked at the manuals:
https://man.freebsd.org/cgi/man.cgi?query=dhcp-options
Ok, added "option option-108 00:00:00:00;" based on that, which dhcpd rejected 🤔
From finding random different examples for custom options and with some trial and error, I found I have instead to declare the option:
option v6only code 108 = integer 32;
... and then use it like this:
option v6only 0;
Ok, what's up with documentation here? 🙄
At least it works, verified on my phone running #Android 14. No #IPv4-address from my pool any more. Instead, 192.0.0.4 appeared, seems it automatically configures a #clat...
