Title: Neighbor discovery reverse dependencies
Post by: keeka on August 25, 2026, 10:42:01 AM
I have the service turned off because I don't perceive a need for it in my case. AIUI only Captive Portal and MAC based aliases/firewall rules currently require it. Is that correct and what other OPNsense functions may come to depend on it in the future?
Cheers.

Hello,

any feature that might use it falls back to NDP and ARP when disabled.

If it's that way forever is unclear right now.
