The branch stable/14 has been updated by eugen: URL: https://cgit.FreeBSD.org/src/commit/?id=057bc783c67e8196d0b8c8c60a7eee6f7dc05805 commit 057bc783c67e8196d0b8c8c60a7eee6f7dc05805 Author: Lexi Winter <ivy@FreeBSD.org> AuthorDate: 2024-05-05 18:21:06 +0000 Commit: Eugene Grosbein <eugen@FreeBSD.org> CommitDate: 2025-10-16 07:12:22 +0000 arp(8): allow -i with -s arp(8) usually disallows adding a static ARP entry for an IP address which is not configured on a local interface. Change this to allow such ARP entries to be added if '-i' is provided to specify the interface the ARP entry relates to. Due to limitations in the kernel lltable, this still requires that a host route exists for the target address, but allows static ARP entries to be configured to proxy ARP for, e.g., local jails which use an IPv4 address with a /32 route.
