[pve-devel] [PATCH docs 1/1] firewall: set default value of NDP to 1 for nodes and guests

[Stoiko Ivanov]

Thanks for noticing and providing the patch!

parts of our documentation are generated based on the information we have
in our JSONSchema and API calls (see e.g. gen-pve-firewall-host-opts.pl
for a starting point)

so the change would need to be done in the pve-firewall repo IIRC:
https://git.proxmox.com/?p=pve-firewall.git;a=blob;f=src/PVE/Firewall.pm;h=ec9c9ae9c35ec31e7cd3ca28ac4b5c20fa7e8c39;hb=HEAD#l1404
