From packet captures you can see solicit being unanswered for a while with that commit applied (or all other SA related commits). As a stopgap I disabled state tracking via: https://github.com/opnsense/src/commit/ee7b012c54 This brings the solicit/advertise back to the state before the SA was introduced. All solicits are immediately answered. No solicits are repeated= by the external router. These are to relevant commits from OpenBSD regarding the matter https://github.com/openbsd/src/commit/2633ae8c4c8a https://github.com/openbsd/src/commit/49f39043a02d You can see that the second commit also disables state tracking for solicit messages like the stopgap patch. Since solicit is the one that is not being answered by a system running the SA I am fairly certain that this is the sa= me problem scope. Anyone got a thought why this could not be relevant to FreeBSD? Cheers, Franco --=20 You are receiving this mail because: You are the assignee for the bug.=
