We have not figured out why the state is not constant After updating our firewall cluster (2 identical machines) from OPNsense version 21.7.8 to 22.7 (HardenedBSD 12.1 -> FreeBSD 13.1) we have problems reaching devices via icmp. To exclude OPNsense here, we started the same system without the applicatio= n, using replicated interfaces with the same result. We were able to trace the problems to arp resolution. For some network devi= ces, arp resolution never works, for some devices it works partially while other devices show no problems at all. With tcpdump we can see that arp requests are being generated but arp repli= es are not received. For some devices the situation resolves by itself or arp resolution goes into a flapping state, with periods where arp replies are b= eing received for some time. We are able to resolve all issues by using static arp entries. ICMP works directly with static arp entries. --=20 You are receiving this mail because: You are the assignee for the bug.=
