hello all, I have finally build an internet gateway with OpenBSD 6.2 (AMD64), including pf and IPSec. Great stuff. Now I am seeing a lot of arp movement, that I know are caused by Apple's Bonjour Sleep Proxy.

On pfSense and FreeBSD you have a sysctl: net.link.ether.inet.log_arp_movements when set to zero it will no longer log the messages. Discussions can be found on internet dating back to 2010, but no solution has been provided for what I could find. I have not yet found any sysctl in OpenBSD to do the same. Did I miss something or does OpenBSD have any trick to not log these messages. Currently these messages are filling up the logs /var/run/dmesg.boot and /var/log/messages. Marco PC
