From 2c0d115bbc8f8ee3f011a5c4a69bcbf58c4b721f Mon Sep 17 00:00:00 2001 From: Kristof Provost Date: Wed, 14 Jul 2021 12:17:03 +0200 Subject: [PATCH] pf: locally originating connections with 'route-to' fail Similar to the REPLY_TO shortcut (6d786845cf) we also can't shortcut ROUTE_TO. If we do we will fail to apply transformations or update the state, which can lead to premature termination of the connections.
